You sure don't need a one ton truck for that small load.....unless you just gotta' have one.
Bought our first truck camper in the early '70s. After three truck campers and three 5th wheel trailers and pulling various size GN/bumper pull trailers to make a living I'm not in the "you can't have too much truck crowd".
Several times I've had too much truck just like I see others have said on rv.net and other rv websites.
Are you looking at a new truck or used ??
If new the only 1/2 ton size truck that can carry 2300-2500 lbs in the bed is the F150HD package. This truck came with up to 7850 GVWR and 4800 RAWR. Older F150HD have 8200 gvwr and the same load carrying capability.
If your looking at older used gas engine trucks ;
...the '00-'06 GM1500HD with 8600 GVWR and 6000 RAWR 6.0 engine 3000 lb payloads will fill the bill.
OR the '00s 1500 Dodge Mega cab with 8510 gvwr and 6000 rawr is good for around 2800-3000 lbs in the bed.
Other wise the market is wide open for a 3/4 ton truck of your choice. These trucks have 6000-6500 rawr and are good for 2800-3500 lbs payloads in the bed.
I would recommend the white one with a high hp gas engine.
