My two cents.....
Last year I bought a 2001 2wd 21' Chinook Cooncourse built on a Ford e-350 chasis, good gearing with limited slip diff. My goal was to use it as a basecamp for boonedocking close to my fishing spots several hours from home. This way I can show up at night, boonedock, fish all day and drive to next location and repeat. Worse case will be fire roads, some can get steep and narrow but generally in decent shape with with little to no off-camber.
Yes, I could do this with tent but at my age I am done with tents and sleeping in rear of jeep, I have done tons of that in past with family, scounts, SAR, and alone.....now I like creature comforts of home and drive-in, drive-out quick and easy.
My RV was stock so I had it lifted 4.5", bigger tires, bigger brakes, fox shocks, radius arms, steering stabilizer, etc. but no 4wd conversion (yet). The RV now drives much better than stock, it might be bumpier but not much, but handling is way better. I was very surprised how well it now drives. My desire for lift was for better general clearance, better approach and exit angles, RV's are crazy low especially with black and gray tank plumping, the lift coupled with Goodyear Duratracs on a 10,0000 lb vehicle give me so much more functionality. I am looking at bumper and wench as added insurance.
The negatives, height. I live on east coast and fire roads are in forests so the height is limiting factor, not so much weidth. However, with any vehichle platform choice you will be making sacrifices. In my search I could not find perfect platform to check all my boxes, my choice was best for me only.
Now 4x4, last year I did not do the 4x4 conversion due to cost and not sure if I would need it. So I decided to give it a year or two, and if I find I really need it then I will head down to Ujoint for the conversion. Chris does great work, super nice, personally accessible and has great reputation.
