They will need Torklift stable loads, Trimbens, and heavy duty shocks at least. At least a load E tires. I have the same truck and have gone to 1 size larger tire than OEM. My camper loaded weight is 3000lbs.
Torklift is a great USA company with great customer service. I recently discovered that I had lost one of my Stable Loads attached to the rear spring of my pickup. I contacted Torklift and they were kind enough to send me out a new one. Now that's service!
I have my Wolf Creek 816 all winterized and cleaned out hoping to sell it this fall. My spouse no longer cares to camp and I am looking at an Outfitter Apex8 to replace it. I have a limited space at my home to accommodate a camper that is not to high.
I have nothing but praise for the Wolf Creek and it has been trouble free. I just need to downsize.
Had reservations in Moraine Park om Memorial Day and the following Tuesday. Weather was somewhat marginal with some wind and showers passing through. Lots of snow in the high country and hundreds of elk milling around and in the meadow below our campsite.
