My 2 cents, even though it's fairly out of date (like everything about me):
I owned a 1977 GMC 1 ton single wheel 4x4 with the t400 trans and the 400 small block, 4.10 gears, open diff. There, that's for the truck nerd... anyway, a basic old 1 ton.
Advantages - relatively cheap to buy, cheap to fix as long as you were ok with junkyards. Lots of steel (not flimsy) and most importantly for today, it sat low to the ground... Half tons today sit higher!
Cons - truck was uncomfortable compared to today's Cadillac ride trucks and it's hi-tech feature was a radio. It was underpowered, 175 HP @ 3600 RPMs. { Torque } 290 FT. LBS @ 2800 RPMs, and struggled on hills, course it weighed over 8000 pounds. The camper probably was 1500 #.
I had an 8 foot camper, hard sided, no bath. Only smoothed out the ride, almost no spring deflection. I had a sway bar so very little sway side to side.
It wasn't hard to get up into since it had to be 2 feet or more lower to the ground than today's stock setups. The camper had all the standard things, small furnace, 2 burner stovetop, small fridg, electrical, cabinets etc. It did have the 4 corner hydraulic jacks which I took off because they stuck out, were ugly and I almost never removed the camper from the truck.
Ok, enough history. Point is, this non-plumbed 8 footer hardside was too much weight for a 1/2 ton and to safely put it on even today's "miracle" half tons requires hundreds of dollars in mods.
Then you need to not have a fear of heights to get up into them.
Shop for an older, lower 3/4 with just an 8' camper and you'll be ok. In Phoenix the very cheapest 4x4 3/4T is $3500 and there's not much choice up till say $5K. T/C's are $2500-4500, so now you have $6-10K plus repairs tied up into a 10 mpg (if lucky) rig. (I got 8)
Anyone who can live in a converted cargo or passenger van knows how to deal with no running water. The TC has the advantages of stand up room and the kitchen.
No vehicle choice will work for everything. It's all what you intend to do with it. There's always somebody pushing the limits with their rig on GVWR or some other measure of safety, but that doesnt mean you should. If you go pop up you can max out a half ton and save maybe $1000 on purchase price and get better mpg. Choices...
