Which Electric Camper Jacks

Thanks. Great input. Interesting comment on the drill. Is there a pretty acceptable screw jack (mechanical) and drill size combination I might prefer? I don't HAVE to go electric, especially if I save big bucks and the one corner at a time is okay. Infrequent use.

No experience with RT.
Happijac: ... 1 motor on my Outfitter seized after only 2 years - water intrusion, completely corroded, motor assembly not rebuildable. Current camper has HJ jacks without motors, I bought a quality electric drill instead.
Atwood: Jacks on our Lance were flawless after 9 years of service, but had to replace controller board once.

Pick your poison, I guess.

I will say that the RT's are fairly easy to service / lube. All you have to do is pull the motor head off (3 hex head screws) and the jack top and gears are exposed. I put some 90 weight gear oil in from the top and let it soak in and run down (it runs down the extension leg) and wipe off the excess) and it's good to go. Not sure about the motors pooping out from salt in the winter, mine is inside all winter in a heated shop. I had Atwood's on my previous Lance and they were no issue either, though noisy when operating.

I like the plastic bag idea. I believe if I used mine in the winter, I'd do the same.

RT's use a thrust bearing in the top to locate the screw jack and it's all exposed when you pull the motor unit off so it's easy to lubricate.

Would be nice if they had Zerk fittings like big truck landing gear so you could grease them externally. Something I've considered adding. Grease is better than oil in my view.

Stay away from Happijac! Granted I use my camper in winter at a ski area in Washington where salt is used on the roads so my jacks are exposed to severe conditions and those conditions are extremely severe if you have Happijacs. The motors leak and are only good for 3-4 years, jacks rust out, even the new zinc-plated 4800s (their best jacks) don't hold up.
I'm now on my 3rd set of motors on the rear and 2nd on the front plus 3rd set of jacks all-around. I will post pictures soon of my 4800s after 3 seasons of use here at the pass, not doing much better than the old powder coated ones.
Customer service used to be top-notch at Happijac, but the parent company (Lippert) has changed that recently.
I would go with Atwood or Reico Titan, campers up here seem to have a lot less issues with them.

My Atwoods have been good, but I did have to replace one remote at 2 years. Fine for the 10 years after.

My 10 year old Atwoods have performed flawlessly

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.

I've had no problems with my Happijacs, although I am not sure they are any better than other brands.

RT. Put them on about 13 years ago, haven't missed a beat.

I like RT myself. RT is an easy company to deal with for parts as well though I've never needed any.
