I saw this at our dealer just before our last trip:
Trailer Aid Plus. If you have dual axles, just drive 1 tire onto the ramp and you can change or work on the other. No messing wth a jack. My trailer's frame is 23" off the ground so I was planning on lots of blocking to use the jack I bought. This looks like a much better, easier, lighter and safer solution.
Anyone used one? Is this new to the market? I've never heard anyone talking about this but was wondering if anyone has one or has used one. I don't see any negatives, only I would watch as it gets older to make sure it does not get brittle.
