Which Electric Camper Jacks

I have had to replace 2 motors for my happijacs. In both cases the motor housing leaked and the motors shorted out. The second I had tried to seal with caulk but it leaked anyway. Now I have gallon zip lock bags taped over the motors. Looks like hell, but at least that might keep them from leaking when I am not traveling. This year I also got a lot of screeching sounds from the jacks. I guess they need to be taken apart and lubed. It seems like a lot of work with potential for error. On top of that I cannot understand either why I should have to lube them or why there is not an easier way if that is needed.

If I had a choice I would definitely research getting a different brand.
