My two cents is … ALWAYS put a cover over the head with the motor. I use one that came with my 2015 Jayco. After a couple of years the motor locked up solid so I had to use the manual adapter. When I got home I took it apart and found the whole motor cavity rusted up. So I took the motor apart and sanded and clean it up and reassembled it. It works perfectly. Now I have a small plastic waste basket that I put a couple locker hooks on the inside to hang the safety chains on to hold it down. While traveling I either hook a bungee from the locker hooks to the tounge or travel without it on. Then put it on while parked. When it failed as I shopped I noticed some brand say sealed and some don't.
