I get where you’re coming from about sand or gravel shifting, but I’ve actually had decent luck with a thin layer of compacted stone dust under my mats. It’s not perfect, but for smaller dips it’s held up better than I expected, even through a couple rough winters. I do agree on the electrical side though—ran into a tripped GFCI last January and had to dig out the cord in a snowstorm. Not fun.

That’s rough. I’ve seen a few setups where folks try to “weatherproof” the connections with those plastic boxes, but honestly, moisture still finds its way in. I’ve had to troubleshoot a couple mats where the GFCI kept popping—usually after a freeze-thaw cycle. As for the base, I’m with you on stone dust holding up better than loose gravel. Concrete’s ideal, but not always practical if you’re retrofitting.
Had a similar headache last winter—my GFCI tripped after a sleet storm, and I ended up crawling around in slush trying to reset it. Those plastic “weatherproof” covers never seem to seal out everything, especially after a few freeze-thaw cycles. I’m curious if anyone’s tried using heat shrink or some kind of rubber wrap on the connections? As for the base, I went with compacted stone dust under mine and it’s held up way better than the loose gravel my neighbor used. Concrete would be nice, but tearing up the whole drive wasn’t in the cards for me either.
Those GFCI trips in winter are brutal. I’ve seen a lot of those “weatherproof” covers fail after a couple seasons—water always finds a way in, especially with ice buildup. I’ve had decent luck using self-fusing silicone tape on the cord connections, but it’s not perfect. Heat shrink works if you can get a good seal, but it’s tough once things are already installed. For the base, I’m with you—compacted stone dust is way more stable than loose gravel, especially with all the freeze-thaw cycles we get. Concrete’s great, but yeah, not always practical if you’re not redoing the whole thing.
Those GFCI trips are the bane of my winter setup too. I’ve actually seen water wick right up the cord under those “in-use” covers—turns out, ice dams are sneaky. Last year, I tried wrapping the plug with butyl tape and then a layer of that self-fusing silicone, which helped a bit, but after a couple freeze-thaw cycles it still tripped once or twice. Honestly, nothing’s foolproof if you get a real wet snow followed by a deep freeze. For the base, I’ve had fewer issues since switching to stone dust—gravel just shifted way too much after every storm. Concrete’s solid, but like you said, not always worth the hassle unless you’re starting from scratch.
