I am planning a trip from Houston to Louisville, KY and then over to Ft. Bragg, NC in the next few weeks. I have a 28 foot Ultralite Keystone travel trailer that weighs about 4900 lbs. dry. It has a GVWR of 6550. The tongue weight is 525 lbs.. My question is, in your opinion, will a 2016 Chevy Tahoe be able to sufficiently pull this trailer through the mountainous terrain between KY & NC? The Tahoe has a 5.3L engine with the 3:42 rear end. It has the Chevy stock towing package (tranny cooler, electric brakes, etc.). I will be using a friction anti-sway control bar. I have pulled this trailer with my Chevy 1500 p/u many times with no problems. The Chevy 1500 also has the 5.3L engine with the 3:42 rear end and stock towing package and I use the anti-sway bar. However, most of where I pull this trailer in this part of Texas is relatively flat. I have not really tried it hilly or mountainous terrain. Your suggestions or comments will be appreciated.
