Hi Bill; I'm not surprised the #T53MR gives you a rough ride since it is the severe service kit. Timbren SES isn't overly forgiving to begin with, and this particular design is for constant loads like a slide-in camper. I would recommend the…

I have attached a drawing from the installation instructions for the rail kit part #C16430-204 you can check out. As you can see in the attached drawing I noted the carriage bolts and where they are located on the rails when installing. Please note…

The difference between the Class II and Class III hitches has to do with their Gross Trailer Weight (GTW), their Tongue Weight (TW), and their Hitch Receiver Size. Class II trailer hitch receivers have a 1-1/4 inch receiver and can be rated up to…

Hey Michael, The Big Truck Big RV Tongue Weight Scale #BTBRV44FR unfortunately can not attach to the bottom of the trailer jack like the etrailer tongue weight scale #e99044 does. The footplate for this scale is held in with a screw so that it…

Hey Scott! Yes, the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat item #277-000164 will turn on at temps lower than 45 degrees. It has been tested and will work with temperatures as low as -32 degrees. I have linked an installation…

The Timbren Suspension Enhancement item #T28MR and the RoadActive Suspension item #RAS54FR can both be used in tandem on your 2021 Silverado 1500 but I wouldn't recommend it. The Timbrens are great to reduce sag but they only engage when your…

The #AL57388 is designed to fit the AT4 and Trail boss models of the 2022 GMC Sierra 1500. Since you have the Elevation with Adaptive Ride Control technology you will need a different suspension enhancement system that is compatible. I recommend the…
