For such a big motorhome, Rover came with a really wimpy-sounding horn. Being built on a Ford chassis, the horn (actually a pair of small horns making two different tones) was the same as you’d find in any light pick-up truck, and on the few occasions when we needed to use it, it sounded like it was coming from a little sedan.

Most diesel motorhomes have big air horns (to go with their air suspension, air brakes, etc.) but we have nothing air-powered in Rover. Following some tips on the Tiffin forum I checked out and then ordered a Wolo Big Bad Max 619 12-volt air horn from Amazon. The horn is directly compatible with the existing Ford horn, which I hoped would make installation easy.

It turned out that while it was electrically compatible, it used a different size 12-volt connector, so a quick trip to an auto parts store was needed before I could complete the installation. While it doesn’t compare to a diesel rig’s big air horns, it’s a huge improvement over the stock horn, and was an easy and cheap upgrade.
