Equalizing pressure on camper jacks

[Siletzspey]

I have Happijac electric jacks on my NL 9'6" QSE.

Question... when I raise the camper off my truck bed, how might I ensure each leg is carrying its fair share of the camper weight?

On several occasions, I've raised the camper only to find one leg *off the ground*. With only 3 legs bearing all the weight, even temporarily, I worry about tweaking the camper body.

To date, I've lowered each leg until it just hits the ground (touch down), and the motor starts to groan from the load. At that point it would seem each leg is carrying roughly-equal weight. The problem happens when I run all 4 motors simultaneously there-after, and the motors don't necessarily run at exactly the same speed over a 12-18" lift. I haven't yet looked at the leg rulers at touch down, and then ensured an equal distance lift per leg.

You aren't going to 'tweak' the camper unless the frame is rotten and then you have other issues. I run mine down until they contact the ground and then switch to the hand crank for a better 'feel' of how much pressure is on each leg / foot.

I never 'camp' with the legs retracted, they always go down. I spent 30 years driving over the road and sleeping in a rocking sleeper on a big truck. I like solid now.

Perhaps common, but you sure can't tell it on mine. All my legs stay firmly planted and none are off the ground for sure.

What he said^
Mine does the same thing. Lifts a back leg a little every time.
Nothing to worry about IMO.

It's not going to happen. The fronts carry more than the back, and one of the backs will always come off the ground leaving three to carry the load. I actually bend one back leg and the camper was just fine on three legs until I bought and installed a replacement.

When I was unloading off the truck as soon as I saw one off the ground I would stop the four and just run the one until it was solidly down again. It's a process, and after a while it just becomes automatic to re-adjust occasionally.
