  • Can Heavy Duty Shocks be Put on the 66 Inch Rack and Roll Trailer
  • The heavy duty Rack and Roll shocks, part # Y08110, can only be used on 66 inch Rack and Roll if you upgrade it with the 78 inch crossmember kit. The crossmember kit is part # Y08111. The 66 inch trailer is rated up to 250 pounds so as long as you're under that capacity there really isn't a need to upgrade it. It would just give you some peace of mind.

  • Can I Tilt Hanging Style Bike Racks With The Bikes Installed?
  • Hanging style bike racks like the Hitching Post Pro # TH934XTR have the tilt away feature but it's meant to be used without the bikes loaded. If you wanted a hanging style bike rack with the ability to access your rear hatch, you'll need something like the Thule Apex Swing # TH9027XT. The only other option is to get this swing away adapter # SAR36VR which can be used with multiple bike racks along with a cargo carrier. The weight capacity of the swing away is 250 lbs.

  • Installing Trailer Wiring Harness for a 2010 Lexus RX 450h
  • If you haven't plugged in the converter box portion of wiring harness # 118255 (the part with the yellow fuse holder) then the 4-Way will not work until you do. Inserting the fuse in the fuse holder would be the last step. This harness is circuit protected. This means that if there is a short on the trailer it will not damage the vehicle wiring or electronics. You should not have to have the vehicle computer flashed or reprogrammed to use the harness.

  • Will Steering Wheel of 2007 Toyota Camry LXE on Tow Dolly Need to Be Locked
  • In order to keep the vehicle on the dolly stable and tracking properly behind the motorhome or vehicle doing the towing, you'll want to keep the towed vehicle's steering wheel locked at all times. This applies whether or not the tow dolly in question is 'self steering' or has a steer axle. I've linked you to some demonstation/description videos featuring the Roadmaster # RM-2050-1 tow dolly you'd looked at.
