Ours is NOT a outside arrangement, Al did want want to have it walk, and besides, that thing is HEAVYYYYYYY, he hated lugging it out every time! UGHAA, lots of moaning and groaning!
He has permanent installation, the installation is found on our web page, below, find link to AL's electrical something or other! (you can tell it has been a while since I edited the home page! HA HA) Look in top left of the page, near the photo of us and Montana.
Good luck with your installation.

BEFORE permanent installation a lock, and heavy piece of chain around the axle kept it secure, then he put on a plastic box to keep out of the wet and mud and slid under the unit near that axle.
