leveling jack question......safe or not safe?

I have a 38' class A. We have a paved campsite that's slopes front to back at a pretty good rate. My question is that is it safe for any wheels to be completely off of the ground? My left rear is off the ground about 6". I put some 2x6 underneath the tires just for peace of mind. I just need to know if this is ok or not. Thanks! Happy independence day! Have a great weekend.

You understand how much weight you're putting at risk on a hill with only 1 wheel holding you...my friend you are living on the edge.

Pacevett,

I've done this a number of times too and learned to chalk the wheels that are on the ground front and rear to keep the coach from moving as you lower the coach back to the ground. You can bend the piston on the jack easily when they are that uneven.

The way I do it now is to use boards to run those wheels up on and use boards under the jack too. This way I don't have to completely lift the wheels off the ground.

The answer is no... If both front wheels are off the ground and a gust of wind happens to smack into the side of the rig the jacks are NOT desinged to take side to side stress and they may pretzel on you .. Very expensive.

And depending on your brakes (My parking brake works on the drive shaft) then if just one rear wheel comes off the ground... Same situtation.

I really don't like any wheels off the ground. With a diesel, the back wheels are the emergency brake wheels so if one is still on the ground you at least have an emergency brake. But like wa8yxm says for a gas coach with the drive shaft emergency brake, anytime you pick up one back wheel, the other is free to roll.

I use 16" long pieces of 2X12 under my tires to get the coach to a position where the wheels are still down solidly when I level the coach.

I have used the jacks to pick up a wheel so I can put the boards under the wheels in a few cases where the slope is extreme and I don't have enough boards to make a ramp. But when I do this, I chock the wheels so the coach does not move in the process.

Rear wheels off the ground is really a bad idea, front wheels not so bad. If you can't get level with the rear wheels on the ground then either move or deal with the out of level conditon.

It seems as if the coach wants to come up to high in the rear when I try to do it automatically. I just retracted all of the jacks and put them down in manual mode. Im not sure if I have a problem or just the nature of the beast. But I feel much safer now that all 4 corners are on the ground. Thanks for the input. Its amazing though how many coaches you see with 1 or more wheels off of the ground.

pacevette, I had the same problem, when I tried to level the rv, with the auto system, it would raise the left rear wheel off of the ground and I would end up doing it manualy, until one day i was under the left rear and found a sensor wire unplug, you might look for something like that, causing your problem. I have the hwh system..

I guess tomorrow I will pull all of the slides in and try to relevel it. Im guessing trying to do it with the slides out is not a good idea.

NEVER have the rear wheels off the ground as that's where your parking brakes act on. Fronts may be OK, We have a Newmar Dutch Star, HWH jacks and Reyco Granning 14,600# IFS.
Newmar says it's OK
HWH says it's OK
Reyco Granning says it's OK UNLESS you have air leveling. We don't.

chalk = chock

chalk is what you use on a chalk board

Some are, some are not. HWH's are so no problem if you have them.

I have always jacked with a wheel off the ground when required without a problem. Now I'm not so sure.
