I am familiar only with the Rieco Titan electric jacks. They seem to work very well. I did have one motor head fail on me and I called the company. They had a new one in the mail that same day, even before I sent them back the old one. Very good customer service so far.
I have heard happijacks called crappijacks many times. i have had three truck campers the best jacks i saw were atwood or reico my happijacks are going back to the factory for the third rebuild i am taking the motors off next week they are 5 years old the last rebuild laasted less than a year i am very disappointed with my happijacks they are a expensive item to replace i will say the factory has been goo about rebuilding them and only charging me the freight both ways maybe i have a lemon could be, i have been very careful in the use of them
