I hate having the hoses and shore power cables sitting on the ground. I saw a picture of this on the internet and I thought it was brilliant. I’ve since lost the link of the original, but here’s my version.
To make this work, I combined two really good (but still inexpensive) suction cups and a pair of mommy clips. The hose and cable goes into the hooks and they go on to the suction cups.
I make sure that I have the hose arranged so the hook is taking the weight of the water filter instead of the inlet on the side of the camper.
I use quick releases all around to save a few minutes during setup and teardown.
