I recently replaced my Roadmaster Falcon 2 Towbar and ran across a product they introduced some time ago called FuseMaster. What is it you ask?
It replaces the fuse you must pull to tow with a switich. Here are the details: FuseMaster by Roadmaster.
We tow a Sturn Vue and the last procedure is to pull the Ignition Fuse from the passenger side fuse box. Now, no more pulling the fuse. We simply set the switch to "Tow" and we are done.
Easy to install and it works. Buy it on-line at American RV Company. Be sure to check the Fit List and this RoadMaster Technical Bulletin to deetermine model for your tow vehicle.
