I agree with the other two posters. If you already have the truck, get something much more doable in weight for your truck. There are a ton of options. Bigger and heavier is not always better, though I used to think so. If it is just the two of you, I’d look at something much smaller with maybe an added awning room. If you need sleeping accomodations for four or more, try looking at a hybrid. Lots of sleeping space, but light weight.
When we got our 26’ Airstream, we were in the right specs for weights. The trailer weighed less than 5000 unloaded and the Tahoe wee were using had a trailering package and was rated for 8500 pounds. When we towed it home after purchase, my husband immediately went and purchased a gas F250. We used it for the years and just traded in for a dieself250. Now you don’t need a diesel or even an f250. That’s not my point. But we love not feeling like we are white knuckling everywhere and that was how we felt with the Tahoe because we had a wheelbase and length problem for the length of the trailer.
