Hello and thank you, I am new here. We just purchased a used 2020 GMC 2500HD 4x4 crew cab. We tow a 36 ft travel trailer. I also have a 96 Chev K3500 that I was towing it with and it did just fine. But being a Michigan truck with only 103K miles on it, I was leery of towing it long distances even though I completely upgraded the cooling system, new brakes in the front inc: pads, rotors, calipers, hoses and rotors. Also new front wheel hubs, shocks and stab links. New rear brakes and lines. New tires even though they had 60-70% tread left, they started to crack in the tread. I bought this truck new way back when.
I feel very confident this new to us 2020 will do the job just fine. The travel trailer weighs 7100 lbs dry. We do not carry fresh water with us and the waste tanks are always empty. We use full hook up camp grounds.
Looking forward to following this forum.
Joe
