So at the time of starting this, I'm done with the initial build, just waiting on Raptor lining. So most of this will be in a single post, but thought I'd share and pass on some of the things I've learned along the way.
For those just looking for pics, you came to the right place lol here's how it sits right now (I'll update this as things change)

First a rundown of what my build consists of
a Harbor Freight "Super duty" 1720lb trailer frame 1720 lb. Capacity 48 in. x 96 in. Super Duty Folding Trailer
Compact Camping Concepts Soft ride spring Conversion Kit Harbor Freight Frame Smooth Spring Retrofit kit
A custom width 3500lb Axle to match the GX's track. as well as 6x5.5lug pattern and brakes Camping Trailer Axle
Compact Camping solution Shock mount kit Weld-on Shock Kit
I ran a 11.5' 2.5" receiver tube down the middle as the spine of the trailer
most of the "box" is 1.5" 11g square tubing, the 4 vertical posts for the telescopic aspect are 1.5" 14g, with 1.25 14g inside, this provided enough tolerance to avoid binding.
really I should have built the whole thing out of 14g and saved some weight...
3/4" marine grade plywood(pressure treated) that was then painted with 10 year all weather paint/stain
Wheels and Tires are take-offs from my GX, I'll eventually upgrade to at least 33's (they're 30's, which I thought were 32's... this will come into play later) but more than likely 34's to match the GX
I did 20g sheet for the body,
Max Coupler for the hitch/receiver.

I added the compact camping soft spring kit

At this point is where I realized... that my tongue weight was too much for my liking already even with nothing really on it... my axle was too far to the rear. When I cut the frame down, I never moved the axle to compensate. I moved it forward 6" and it's perfect.

I towed the trailer home and it towed awesome. the max coupler really made it feel connected it tracked amazing

I test-fit the tent on(mainly because the tent was taking up the spot in the garage... so I had to put it on so I could get the trailer into the garagePXL_20230402_195650518.jpgPXL_20230402_195652648.jpgPXL_20230402_195708808.jpgPXL_20230402_200224866.jpgPXL_20230415_205412264.jpgPXL_20230415_220259188.jpgPXL_20230415_220308215.jpgPXL_20230415_220340499.jpgPXL_20230415_220358886.jpgPXL_20230415_230923155.jpgPXL_20230415_230943534.jpgPXL_20230415_231137642.jpgPXL_20230415_231145278.jpgPXL_20230415_231907722.jpg
Here's the support I built to support the fender so I can use it for a step or as a mount

I ended up having to move this bar up about 5"s to allow clearance for 34's... This is the point I realized that my fender was too low because I was using my stock tires to get measurements, and I thought they were 32's, when in fact they were 30's (I think i would have been too low even if they were 32"s now that I look at it) thanks @Codeman and @PapaDave for calling this out that!

Sitting my 34 spare in front of the stock to see about clearance. the fenders are built to allow a 35, so they're wide enough...it's jus the camera angle that makes it look like they'll hit
test fitting the 34 spare so I could get proper placement of the spare carrier so I don't make the same mistake as I did with the fenders Pulled it all apart to paint the plywood, primer all the bare metal, and grind down all the welds to prepare for skinning.

I put on about 150' of VHB tape to hold on the sheet metal and trim. at 35 lbs of adherence per inch I'm confident it's not going anywhere LOL also threw in some construction adhesive in a few areas, and some seam sealer to ensure it'll stay dry inside.

Due to my lack of pre-planning, I ended up with a gap between the fender and the wall... took a great idea by @PapaDave

And here it sits. ready for Raptor lining.

got some shots from my buddy, here's the first coat of Black Raptor (the bottom got a heavy coat, top just a light coat, as it'll get covered with a color matched coat)

Nice build, I'm looking at doing something similar in the future so seeing stuff like this is great for inspiration and ideas. One suggestion though and you might have already done it, is to drill a hole in the bottom of the 1 1/2" vertical tube for your telescoping system. It will collect water and dirt and you'll need a way to get it out. It would really suck to have it rust out or get water in and freeze. On a different note, have you ran it across a scale yet or know about what it weighs so far?
Again, nice build!

Good point. The tent will hang over and cover, but a drive in a downpour will still end up with water in tubing. I'll do that for sure!

I will hit the scale this weekend for sure. I'm not really sure what to expect for weight... Thinking 700-900lbs? But that's a true WAG lol

Excellent work! thanks for sharing the build. Looking forward to seeing the final product.
Thanks! I'm anxious to get it out on the trails. I have a plan for interior build out of drawers and slides. So "final product" is a relative term

I've built some things in the past and had them get messed up from water getting in so wanted to spare you the headache. Another idea I had looking at your build and this one might not be as good. You could cut down your 1 1/4" legs a little bit, cap the ends and find a coil spring to drop down the 1 1/2" tube for some spring assist in your lift. It would take some searching to find the right diameter, length and spring rate but would make it nice to have it lift at least part way on it's own. If the spring rate ends up pretty stiff to get enough lift you could use cables/pulleys with a crank to compress it and control the raise.

While looking for ideas for a trailer build I came across this folding table and thought it might be handy mounted to the side of a trailer. Not sure how sturdy they are but I have a few of their triangle toolboxes on farm pickups and they're built plenty stout.

I have 60 lb gas struts that will lift the top when the pins are pulled.

Ok got the Raptor done. not super happy with the color, but wasn't really ever chasing a matchy match look. PXL_20230510_010048905.jpgPXL_20230510_011719903.jpgPXL_20230510_012217747.jpgPXL_20230510_012227415.jpgPXL_20230510_012250179.jpg

Glad to see you got it done. I just did 3200 miles with mine. You certainly find out what you need to re-do after 2 weeks and dragging it a crossed 6 states.
Nice where all did you go?
I thought I might have passed your GX outside Sandpoint yesterday on my way home.

Just got back from the "shake down run" a 1500 mile trip through Canada and Montana. Tons of rain, but no issues with the trailer, minus my table catching on my license plate light wiring when I pulled it out and disconnecting it.

I hadn't done the seals for the doors and still had next to no water inside (we saw about 6"of rain in our 7days of travel) and very little dust (ironically saw some pretty dry areas on the Alberta side)

Met up with @Codeman and family in Montana to surprise the wife.

A custom width 3500lb Axle to match the GX's track. as well as 6x5.5lug pattern and brakes Camping Trailer Axle

I ran a 11.5' 2.5" receiver tube down the middle as the spine of the trailer
most of the "box" is 1.5" 11g square tubing, the 4 vertical posts for the telescopic aspect are 1.5" 14g, with 1.25 14g inside, this provided enough tolerance to avoid binding.
really I should have built the whole thing out of 14g and saved some weight...
3/4" marine grade plywood(pressure treated) that was then painted with 10 year all weather paint/stain
Wheels and Tires are take-offs from my GX, I'll eventually upgrade to at least 33's (they're 30's, which I thought were 32's... this will come into play later) but more than likely 34's to match the GX
I did 20g sheet for the body,

I chose the HF Frame for 1 main reason, ease of titling in Washington. I've heard tales that ever since covid, the state police aren't super responsive with trailer inspections (admittedly I never even tried) I cut this down from a 4x8 to 4x6. and welded it (as well as bolts just because) looking back, I probably should have just built the frame myself, as much of my initial issues were trying to make my design fit the HF frame. and so I had to make several design decisions around it. it's also the weak point on my build, not that I think it'll fail, just that I overbuilt the rest.

Sitting my 34 spare in front of the stock to see about clearance. the fenders are built to allow a 35, so they're wide enough...it's jus the camera angle that makes it look like they'll hitView attachment 257139View attachment 257140View attachment 257141
test fitting the 34 spare so I could get proper placement of the spare carrier so I don't make the same mistake as I did with the fendersView attachment 257142
Pulled it all apart to paint the plywood, primer all the bare metal, and grind down all the welds to prepare for skinning.

I put on about 150' of VHB tape to hold on the sheet metal and trim. at 35 lbs of adherence per inch I'm confident it's not going anywhere LOL also threw in some construction adhesive in a few areas, and some seam sealer to ensure it'll stay dry inside.

Due to my lack of pre-planning, I ended up with a gap between the fender and the wall... took a great idea by @PapaDave

Great build! Can’t help but notice the ford in the background. Is that 58? Anyhow both builds look great!

Honestly I have no idea, it was a buddy's shop that he was extremely gracious about me using. He has quite a few rigs in there.

Just got back from Northwest Overland Rally, and got to test the trailer on their technical course, worked amazing. the Maxcoupler really shined and 0 issues, only a light drag of the hitch nut on the receiver cresting the top coming out of the last "pit" which was about 7' deep.
