Lots of well though through information here. My thinking is that all campers are heavier than advertised and even a light camper with the attributes that you are looking will be in the high 3000 to low 4000 lb range. My Wolf Creek which is advertised by Northwoods to be a 1/2 ton camper weights 3000lb loaded. I have beefed my 3/4 ton pickup truck up with stableloads, timberns, and new heavy duty Blistein shocks. I also have oversize tires albeit they are not 19".
I pretty much of the opinion that anything heavier than a 3000lb camper needs a DRW truck. I've had a DRW Ford when towing a fiver and know that they are a PIA when used for purposes other than towing. By that I mean using it for a daily driver.
Hope you get the information you have asked for to make an informed decision.
