Expert Answers about Thor Quantum Motorhome


  • Front and Rear Air Bag Suspension and Onboard Air Compressor for a 2022 Thor Quantum KW29 motorhome
  • I would be happy to recommend an air bag system that will upgrade your 2022 Thor Quantum KW29 motorhome's suspension. For the front axle you will want the Firestone Coil-Rite Air Helper Springs item # F4101. These fit inside your front coil springs to keep your motorhome level. This system will improve steering control and balance. For your Thor Quantum's rear axle I recommend the Firestone Ride-Rite Air Helper Springs item # F22ZR. These air springs have a 5,000 lbs capacity and reduce...

  • Rear Suspension Enhancement for 2024 Quantum RV KW 29
  • If the rear suspension is sagging and that's why it's bottoming out and dragging an air bag kit like the Firestone part # F22ZR would be a really great option to fix that problem. With added air pressure in the bags this would raise the rear and get rid of the sag. Then for a compressor that would allow you to control the air pressure from within your motorhome the Firestone part # F2219 would be a great solution for that as well.

  • Recommended Steering Stabilizer For A 2022 Thor Quantum SE22 Class C Motorhome
  • The RSSC and RBK24 would be a compatible fit for your 2022 Thor Quantum SE22 Class C Motorhome. It looks like we currently do not have these components available so the alternative would be the Roadmaster Exact Center Steering Stabilizer w/ Custom Brackets # RM47MR. This stabilizer uses high pressure nitrogen gas and a steel rod to compress and spring back against to help keep your wheels straight instead of the RSSC's shock and coil spring design.

  • How To Wire In The Monitor Light For The Roadmaster InvisiBrake Supplemental Braking System
  • The monitor light for the Roadmaster InvisiBrake Supplemental Braking System # RM-8700 would need to be grounded to the chassis of the motorhome. The LED light and audio signal will both have a wire to run down to the chassis and another wire to run over to the towed vehicle to connect to the cold side of the brake light switch.

  • Can I Use the FloTool RhinoRamps for Dual Rear Tires?
  • These ramps will work with your 2022 Thor Quantum but I do recommend using two sets for your rear end especially if you are going to be underneath them working. The FloTool RhinoRamps Max Vehicle Ramp Set item # FT11912MI are only 11-3/4" wide. They do have a 16,000 lbs capacity per set but I would feel more comfortable with having two of them on each side for balance when lifting up a dually.

  • Where to Mount SiriusXM Vehicle Satellite Radio Antenna # R169159
  • The actual antenna (or puck) part of the SiriusXM Vehicle Satellite Radio Antenna # R169159 is magnetic so you can mount it inside or outside of your vehicle. If you wanted to use an adhesive for more of a permanent installation you could do that as well. Some people will mount it in a window for an easier install that still works great without having to get it outside of the camper. That's honestly what I would do.

  • Recommended Sway Control and Shock Absorption for 2021 Thor Magnitude 35bb with F-550 Diesel
  • For your motorhome, the tire pressure should be whatever the manufacturer recommends which should be in the door panel sticker or your owner's manual.

  • Steering Stabilizer and Anti-Sway Bars for 2022 Thor Quantum KW29 Motorhome
  • The best way to enhance the ride of your 2022 Thor Quantum KW29 on the Ford E450 chassis is to add an aftermarket rear anti-sway bar because it acts as a brace between the frame of your motorhome, and is constructed with higher-strength, thicker steel than OEM sway bars. This means it has much higher roll stiffness to combat sway - the higher the roll stiffness the better sway control - and its placement at the rear of the vehicle allows for the greatest improvement in handling. After...

They have a no-drill installation and are totally maintenance-free. The SumoSprings have a 30 day satisfaction guarantee and come...
