The new BFG KM3s come in that size if you want something more aggressive. I really wish that more companies were offering a better variety of tall and skinny tires. A 35x10.5 would be my preference. Kenda is the only company producing that size though.

i wish i got double digit mpg's....
my crew pulls down a "staggering" 5 mpg's
living in the mountains means no matter which way i go i run into 8-15% grades, anywhere from a mile long up to 20 miles long. with the camper on board and the trailer in tow, it can and does drop down to a wallet busting 3 mpg's on the bigger hills.
it cost me a buck a mile to drive it. to fill both tanks is $200. around town i can get about 180-190 miles on both tanks, on the freeway about 2-210, or roughly averaged out- a buck a mile....
What are you driving?

Geez. I had a diesel pusher and stacker trailer that weighed over 53k lbs combined and I'd still get high 6s MPG in hilly country.

Is the truck tippy with that camper?
I'm a little worried about wind and such if I go that route. My truck should be a little heavier, and rhe campers I'm looking at are a little smaller. Capris Retreat, Bundutec Bunduvry, etc. etc. Right now my truck fits 35" tires stock, but a 4" system would smooth out my dirt roads nicely.
-------------------------------
Mileage #'s are sketchy without grade info, stop light count, wind, etc. City mileage figures are assumed 1mpg.
Cruising at 80mph on flat ground with my F250xl wheels and tires I get 15mpg.
Drop to 70mph and it can climb to 17, rarely even 18mpg.
MT tires and it's 14-15 everywhere.
Skinny work truck wheels and steady speeds work wonders.

ya, oil burners are much better on mpg's, pretty much what ever their installed in.
bet you don't have 42" tires on your pusher though...
a healthy big block, a trans with a 1:1 hi gear and 4:56's in the axles equals 32-3400 rpm at 55mph...glug glug glug
205 t-cases don't like to be spun much faster than 55 anyways...lol
also got the aero's of a barn door and a loaded weight of 16 k
some modifications done to it, none really done with an eye to fuel economy, more so for capability in the bush

Super cool truck, a bad arse old-school is worth the pain of the MPG. Have you considered adding modern EFI to help out some? The newer systems are getting so good, and there are several (including Holley) that make kits that replace the carb and are self-learning/tuning?
FWIW, the tires on the pusher actually were about 42"s. They were 315/80-22.5 in all 8 places which works out to about 42.3". So yes, 42"s and over 53k lbs combined.

I drove supers in the mountains, Vancouver to Edmoton, 130K pounds and never got worse the 5mpg. You NEED to buy a new truck. But I guess if you stay close to home..... But you make the case for stock rubber. Buy some new 235/85R16s and they'll be free before you mile them out..... Ego is darned expensive.

I just pulled this from my maintenance app. The past 365 days of fuel use. 1995 Jeep XJ. That last refueling of 11mpg was all off pavement.

70 FJ55 with SBC 350 EFI, 4.10s and 35in tires. Last trip with gear for 3 people I averaged 12 mpg over 2500 miles. Several hundred miles on dirt roads. I am hoping to increase the mpg when I put the 5.3 LS in this winter.

Just came back from 3 days in Death Valley fully loaded. We did 1250 miles and of that about 170 miles of dirt with lots of crawling. 22.05 mpg.

Interesting to look back at my July 2017 post in this thread before I got my trailer (avg 20-21mpg), then my Sept 2017 post after driving from Maine to Oklahoma (still no trailer but all interstate miles at avg 21.3 mpg), then own and tow the trailer all over hither and yon the last couple years to the tune of around 600 nights out.
I experimented on my last long adventure towing the trailer--eight months and just over 17,000 miles--and didn't touch the DIC mpg figure the entire time and avg'd 17.3 mpg. That includes miles driven without the trailer while it was set up as basecamp and a fair bit of idling time here and there. Almost all miles not towing during this time were back country or two-lane at 40mph or less.
What I've found over the years with this van, in religiously keeping track of fuel receipts and gallons consumed, is that the DIC is actually quite accurate. My initial figures after I got the trailer in '17 were that I was losing around 4 mpg towiing the trailer. Interesting to see that's held true over a couple years and a gazillion miles.
Considering the size of my van and trailer and the considerable amount of gear I haul for long term slow travel, I'm pretty happy with 17.3 mpg when towing.

I have a 2019 Tacoma SR DCSB 4x4 auto with a shell on the bed. No lift or whatnot. It has the TSS package that came with 17's and 265/65 AT tires. I deliberately kept the exterior as slick as possible and tried to keep the weight down by only adding stuff I thought I needed for what I do. No lift, no steel bumpers, no external racks, no drawer system, etc. All of my recovery stuff and camping gear is contained in the shell. The goal was to be lean and mean for trips and keep it simple. When the bride and I went to Smoky Mountain National Park from DFW there were times we were getting close to 24mpg (23.7or so) on some stretches. Daily driving I get about 18.5-19mpg.
