MH slide operation slope tolerances?

I own a '07 KSDP 3912 with three slides. The street in front of the S&B slopes. I have been using my Levelegs to get the coach to almost level when we load it or unload it. It sure seems to place stresses on the levelegs horizontally ( which I am pretty sure they are not designed for much).

The slope front to back is down in the back by 1.7 degrees the left to right is down on the right by .8 degrees.

Looking at the fridge, located on the driver side of the coach, I've been told it will work out of level within this tolerance. My question for you Newmar experts: Can I open,the slides at these angles without damage or harm? Hence, not stressing the levelegs

This is a general question that all of us have, and there are various opinions.
Normally, everyone agrees that level is best...but that is not what you are asking.

Things to consider.
1. Twisting your chassis is never good, and can even crack a windshield.
2. Slides are not fully supported by the mechanical system, most of the weight is on the rollers.
3. Anything not level will introduce a vector force that can make the slide move forward/backward in the opening. This can cause some stress on the mechanical parts of the slide system. You might notice that gaps are no longer even.

The best you can hope for is enough opinions so that you can form your own, based on your comfort level.

The slope you have is not excessive for opening the slides. The question is wheaten the the opening for the long flush slide is distorted by the leveling or not. Check the gap around the longest slide. If it is not closed ( most of the time if it is closed it is at the front upper corner) you can open the slides. If it is binding, don't open it, damage may occur.

I'm super cautious about my slides and my leveling jacks - probably overly so because I have a little older rig. That said, I think it would probably be kinda-sorta ok to open your slides, but personally I'd only do it if I really needed to.

If this was a park I was staying in for a couple weeks, that, for me, would make it worth the risk. If it's just to make loading and unloading easier at home, that, for me, wouldn't be.

But it's your rig and your comfort level, so good luck whichever you choose.
