I'm retired and my wife is going to pack it up in October, if not before. We were avid campers back in the day. Not so much lately and were hoping that is about to change. We started out tent camping, moved up to pop-ups, then finally to travel trailers. Never owned any class A, B, or C RVs. We attended an RV show over the weekend and that got the juices flowing again. The heaviest I towed was the 20 ft. travel trailer and it was a challenge for the GMC six cylinder I had. I honestly can't remember what it was rated for pulling wise but I know I was close to it's limit. In hindsight, I should have paid a lot more attention to this and was lucky I came through it OK. Pondering on my past raised some questions I'd like help in understanding moving forward. Firstly, what determines the towing capacity for any vehicle capable of towing? Is it HP? Drive train? I would guess both but what else is considered? Secondly, what are the long term implications on the vehicle with constant towing at the maximum tow rating on a vehicle? As an example: My Sierra has the six cylinder in it and is rated at 285 hp. It also has a towing capacity of 6200 lb. What would you consider the most you would tow with this vehicle and not be concerned about excess wear on the engine and have it live a long and happy life? 1/2 of the posted capacity? 2/3? Would you tow to the limit every time and feel comfortable about vehicle longevity? These are questions I need more information on as it will likely affect any purchase we make. Sorry if I rambled and I hope you get the gist of what I'm asking. If you need more info on my specific vehicle or needs, please ask.
