Yet another what can I tow question

Agree with above, your payload and hitch rating will be limiting factors. Most figure a loaded trailer hitch wt of about 13 percent, so an 8,000 lb loaded to camp trailer is likely to be just over 1,000 lbs hitch wt. Depending on your experience/comfort zone, I'd say 6,000 unloaded/dry wt, to a GVWR of 8,000.

Many figure to add about 1,500 lbs to whatever their trailer weighs empty.

Keep in mind the wt added inside truck, and truck bed, which is added with the hitch wt, as is the weight distributing hitch, another 100 lbs, to get total payload.
