We have a 2014 Tiffin Allegro 36LA with HRH leveling jacks. When we deploy the jacks using the "auto" mode, we frequently get an "excessive slope" indicator, even though the coach is sitting on basically level ground.
When we talked to our service department, we got 2 answers: 1) the jacks probably just needed to be recalibrated; and 2) this is a problem with the gas-powered coaches. The coach doesn't "kneel" like a diesel does, and so the jacks almost completely extend just to reach the ground and therefore don't have much lifting/leveling capacity.

We are not crazy about having to crawl under the motorhome (we live in the Pacific Northwest and do a lot of winter camping, when it is often raining) and put blocks under the jacks, and we are concerned they wouldn't be very safe due to potential slippage. We don't see this as a viable alternative.

Has anyone else had this problem and how did you resolve it?

We've had the out of range light in both our Open Road and our Phaeton and sometimes those sites that look level, just aren't. We have any found concrete pads in better RV parks which appear level and you can't level on them. We carry some blocks with us for those occasions and put them under both the wheel(s) and the jack(s) that are low.

Our pads are approximately 11" X 11" x 3" (2 - 2 x 12 screwed together and right angles to one another) and when the MH is sitting on them, it isn't going to move. These are also very handy on soft ground. You can add a screw eye or rope to these to make positioning and retrieving them easier.

If you think the your leveling system is off, take your coach to a parking lot that you know is level or near level and put the jacks down. Use level on the floor of your coach and see how level you actually are compared to what the leveling system thinks you are. You can adjust it yourself but since you are under warranty, let your dealer do it.

You are under warranty and that is not correct about gas coaches. Yes it may need recalibrating but it can also be a bad control board. You need to contact Don't Boyd at Tiffin. I don't have his number handy but his email is www.don.boyd@tiffinmotorhomes.com

I have owned 2 gassers and both would pick the tires off the ground. Some jacks were they bolt to the frame are adjustable maybe they can be lowered down. There is no way you should have to crawl under your coach for leveling take it back.

We also have a Allegro 36la. We have fortunately, never yet had the issue you describe. As a former service writer though! I do know that talking to the service dept isn't going to be any help whatsoever. The problem cannot be diagnosed without seeing the coach. Whoever you talked to is simply guessing, and likely not even an educated guess.
Take the coach in, get it checked out. You could take the coach to a known level spot and deploy the jacks to confirm if it is indeed ' mis-reading' the levelness. But a correct diagnosis can only be made by a technician going through the proper diagnosis sequence.
In regards to jack pads---We bought a set of Hoss Pads. They are great and I highly recommend them. They are roughly 9 inches square and 1 inch thick and have rope attached to make retrieval easy. We happen to have a telescoping aluminum pole with a hook on one end. I can push the pad into position under the jack before deploying, and then when the jacks are lifted use the hook to retrieve. My knees and hands never touch the ground. I have seen my neighbors use a old broom handle with a hook screwed into the end with the same good results.
Good luck to you, and please post what they find on your coach!
