Before you do anything else, I would weigh your new trailer at a CAT or other certified scale. That way, you can determine your actual tongue weight and trailer weight to assist you in shopping for your new vehicle. Just make sure that you load it down with what you would be carrying with you for your typical camping trip, water in the tanks, etc. when you head to the scales. (Borrow a friends truck to take the trailer to the scales if you don't want to use your current Tahoe)
I see that you are from the Pittsburgh area. I always use the CAT scale at the truck stop in Smithton PA, just off of RT-70.
