What PU to Buy

I towed my current TT (about 5000 lbs loaded) for a season with an older Silverado 1500 and hated it. The 4 speed constantly searched for the right trans gear and it really had to wind up to produce power. Hills with the 5.3 were a struggle and it always felt like a good breeze was really pushing me around. I replaced the 1500 with a 2500HD this season and the handling was night and day difference. The 2500's stiffer suspension and heavier brakes make for a much more enjoyable and less stressful trip. I didn't make it to the scales with the 1500 but I bet I was close to the payload max with the family loaded up for a trip. I'm sure the newer F150s (ecoboost) and 7 speed Silverado 1500s are capable of towing 6000k lbs but IMO you would be more comfortable with a F250/2500 with that weight. I'd love to get a diesel one day but it just isn't in the budget.
