  • Trailer Hitch Recommendation for 2007 GMC Sierra Classic 1500
  • For your 2007 GMC Sierra Classic 1500 the hitch I recommend is the mostly hidden and higher capacity Curt Class IV part # C14332. This hitch installs easily, has more towing capacity than you'll need, and since it's mostly hidden looks better too. I attached an install video for this for you to check out as well.

  • Could Trailer Go From Tire Size ST205/90-15 to ST235/80R16
  • The ST235/80R16 has an outer diameter of 30.9 inches whereas the ST205/90D15 has a diameter of 29.5 inches so the diameters are pretty close. They would be close enough that there would be no issue going from one size to the other. For that you could use the part # LHACK133 for this size mounted on a wheel with a 8 lug bolt pattern or part # TA59VR for a 6 lug bolt pattern. Worth mentioning is that the tire size you have now isn't a standard trailer tire size and it's not recommended...

  • Yes, we do offer custom fit (no drill) under bed 5th wheel hitch mounting kits for your 2007 GMC Sierra 2500 Classic. However, please note that the no drill is in reference to the frame brackets because you will need to drill through the bed floor no matter what to install a 5th wheel hitch.

  • Lift Kit for a 2017 Forest River Rockwood A214HW Camper
  • According to my research, your 2017 Forest River Rockwood A214HW Camper has Dexter Torflex Torsion Axles. I looked up the weight capacity of your axle and seen it was 2,300 lbs which means the Torflex Lift Kit part # K71-707-01 should be what you need. This kit will provide you with a 2-5/8" lift but please keep in mind it is not recommended for use on torsion axles with 3" high profile brackets.

  • Best Brake Controller Recommendation for a 2007 GMC Sierra 1500 Classic
  • For a brake controller for your 2007 GMC Sierra Classic I would recommend the Prodigy P2 Brake Controller part # 90885.

  • Recommended Air Pressure in Firestone # F2250 Ride Rite Air Springs for Towing Fifth Wheel
  • The # F2250 Ride Rite system needs a minimum of 5 and a maximum of 100 psi. The proper air pressure for towing your fifth wheel would depend solely on your personal preference. I'd start at about 50 psi, and make some test runs. Add or lower air pressure until you find which level provides the most comfortable ride. You'll eventually find a comfortable towing and non-towing air pressure.

  • How to Choose Correctly-Rated Weight Distribution Hitch
  • Replacing your friction-style sway control device with a weight distribution system that includes integrated sway control will give you a substantial jump in handling quality. The best integrated systems actually prevent sway, instead of trying to only react to it like the friction bar systems do. The ideal is to have your total effective tongue weight (TW) - the combination of the loaded trailer's actual measured TW plus your behind-the-axle cargo weight - right near the middle of the...

  • What would Functions of Black and White Trailer Wiring Colors be
  • Typically white is ground and black is power based on standard trailer function/colors. With that said not all lights and trailer wiring follows the standard colors. You can use a circuit tester like part # PTW2993 to test the wires when the various taillight functions are applied though to verify for certain.
