Couple questions for ya as I’m about to pull the trigger on a 5x9 extreme off road as I’m towing with a heavily modified Jeep Wrangler 4door on 37’s. Do you like how much room you have inside? And would change anything with your galley?
My home bilt is 5x10, tons of room. I store my doors in the front 2'. Depends on how much you pack.
I'd say 5x9 is perfect, fits a full size mattress for 2.
The 5' wide behind a Wrangler has 2 big advantages.
The stock mirrors can see past the 5' wide.
And reversing you can see both sides of trailer, keeping it straight is easy.
The skinnier 4' wide and ultra short Expo trailers can fuck off before you see them.
