I don't mean to be unreasonable and everyone has considerations.
If someone showed up at my door with a DRW truck with a manual transmission, I would probably trade them. I never expected that I would want or need a DRW truck. But given that carrying a camper requires serious payload, in hindsight, I wish I'd got one. I expected to TOW a camper when I bought a 1 ton SRW. Now, knowing that I'd prefer to CARRY one....a DRW truck is the ideal option in my view.
If you already have a truck, fitting a camper to it may involve compromise. If you don't already have a truck, get a DRW! Consider even getting a 550/5500 if the budget allows. Nothing wrong with picking the camper first.....but picking the heaviest duty truck allows you to pick whatever camper you want.....which to me is worth it.
