I would like to send a huge thank you to d3500ram for sending us the pdf file for the happijac maintenance and to KKELER14K for the Outstanding write up on Happijac maintenance. I am firm believer in proper lubrication. Since I have not seen the inside of these jacks, I will feel much better once I have taken them apart and understand what is going on inside and knowing that they are properly maintained.
On the other hand, if these jacks are that temperamental in regards to being perfectly level, I would have to say they may be inferior to others on the market.
Our previous camper was an S&S 8' short bed model with 20 year old Attwood electric jacks. never once did they bind up and never once did I have to use the hand crank on them and never once did I do any maintenance of any kind on them.. The first time I used the Happijacs
(that show no signs of corrosion on the outside) I had binding problems, and I did have the camper level as I always did with the S&S.
That being said, It is a big pile of cash to switch brands , so I want to make all efforts to make these Happijacs work.
Thanks again to all of the great advice, and wish us luck please. This is a very valuable forum.
Doug
