BBVD,

Your first photo link doesn't work.
Why are bashing Happijacs or are you bashing all corner jacks in general? I personally haven't any any problems with my HJs and they've been on my TC for eleven years.. I've only had to replace one part, a Torrington bearing in that time. I disassemble them every two years and relube them.
Are HJs the best .......probably not but mine have lasted and have been reliable.
I'm not a paid spokesman for HJ.......Do you have an affiliation with Stable Lift as I see this is your first post?

I've put in the addresses of the images... just copy and paste the address in the browser.

I'm not affiliated with anyone. You can see my annoyed wife in one of the pictures going "We just got this thing!"

HappiJack is a flawed system. Titan is awesome, Atwood has a good quality heavy duty corner jack. Overall, the HappiJack system was designed 20+ years ago before sliders were a thing and campers were 2500-3000 lbs. Now a single, dual or even triple slide campers can be 4500 lbs or more. Other manufacturers have adapted to a better system and HappiJack has not.

Simply put, if you remember your high school physics class, round is better than square regarding load bearing structures, especially when considering side shifting loads. HappiJack is a square tube and as you can see from the first picture it collapsed along the flat side due to a slight shift on the center of gravity.

I'm actually a proponent of anything that will keep my family safe. Stable Lift is an incredible product and because the corners are destroyed on my camper that's the only system that will work from here on out. I will say this, I was looking at it before this happened and I would have switched over sooner if I was more aware of the safety and reliability issues regarding the HappiJack system on the camper.

If used properly, most corner systems will be great but HJ is not one of those. As I said, due to the jack system design and the sheer weight of the AF 1140 and 1150 campers all you're doing is playing with borrowed time until one of those collapses on you.
