We don't always skirt motor homes. But when we do, they look $#&#ing amazing. This lucky sun of a gun has a pretty plush setup with the concrete pad that I'm sure he loves.
It is worth noting here that our system works great with concrete as well as grass lots. You will note the sand bags he has places arround the RV skirting. Those will keep the skirt held to the groud just as well as our 10" spikes. You will also note the the skirting isn't tied in as the images were taken as we were part way through the install process.
