Turns out, they don't have my size yet. My pads are HWH hydraulic and are 8" in diameter. The product only comes in 9" diameter at present. The VP of Operations answered my email question yesterday within minutes and said they are coming out with other sizes early next year.
Those thinking that they are too expensive, and who make your own for just a few dollars...yeah, you're right they are too expensive. BUT...I tend to stay at older, remote, out of the way RV parks and often run into conditions where I'd prefer not to have to crawl in the mud, dirt, stickers, weeds, or gravel in the rain, wind, or dark, to push pads under my jack feet. Even with an extension push wand and hooks on the pad.
This product remains on the pad so there's nothing that needs to be done except drive into my spot, and press the jacks down buttons. And they widen the stance of the landing pads to reduce the number of times my pads will sink, hopefully to zero. I've already had my rig sink here at a RV park in the Mojave Desert. Sunk into soft dirt 3".
Too bad they don't have my size yet. So I don't get a xmas present this year.
