Bigfoot Question (From TapaTalk Forum)

When I recently replaced my wheels and tires, I used the leveling jacks to raise the trailer of the ground.
I found that if I used the right and left pair of jacks, the system would only allow me to tilt the trailer about 1-1/2 degrees out of level, side to side before it would stop me. I would then have to manually re-level before I could raise the trailer anymore.
Are we better to raise the trailer using the front and rear jacks in pairs, rather than the right side and left side jacks in pairs?
I guess I could try it and see, but I thought it would be nice to hear the official answer.

And I know the literature says you shouldn’t do it. But! I spent a week on the jacks with no wheels when I had the hydraulic disk brakes fitted, and no problems. Was pretty sturdy, no shake too.

I do remember something written somewhere about jacking up the RV for tire changes. I know the BF will support the entire RV off the ground. The main thing that I remember was to jack the RV up evenly front and rear so as not to twist the frame. I jacked up mine once so I could remove the wheels to check the grease in the hubs. You don’t have to jack it up too much to clear the tires from the ground. The other thing you could probably do, but it would not be as secure as having one set of tires on the ground is to raise both set of wheels off the ground using just the rear jacks. However, I don’t feel this would be as stable as having the opposing wheel and jacks on the ground while working on the other side.

Also, to re-level your unit, you would have to raise the rear jacks, bring your front end higher than the rear, then press auto to re-level your RV.

Good luck!

Sheff,

I Don’t have an official answer, but in my (limited) experience, left/right tilt is much more sensitive than front/back. I had an issue with the system, and while on the phone with Rick, tried to level manually in a poor site. At a little over 1 degree side tilt, Rick was saying that that was quite significant. I’ve had the trailer in my driveway with about 10 degrees forward tilt with no problem. I’m sure it’s about weight distribution and center of gravity. With the jacks at the outside edges, there’s little to counterbalance side to side, there is always weight both fore and aft of the front and rear jacks.

I too will now wait for an official answer.

As I recall when you jack your trailer up using the BF not to move side to side more than 2” at a time. I’ve done it several times with no problems.

I have used my BF both to lift one side at a time and also used the back levelers to pick up the wheels for a tire repair. Just from an operator’s point of experience, I felt the coach was more stabile and I was more comfortable with using the rear jacks for the proceedure. It might be the wrong way, but it is my experience.
