Self leveling

It is indeed and no you can't:). But it illustrates less need for jacks in a shorter van.

Don’t follow you’re logic there I’m afraid :)

If it’s on an angle it’s on an angle length if vehicle is immaterial :)

Still that’s enough from me :D
 
How level is "level" -as far as fridge needs to be (gas on 3 way ) ,I have round bubble level stuck on dash set up level to fridge and as long as its within the two rings on the bubble its OK ?

Never had much of a problem as long the the wine glass doesn't fall over the fridge works OK. Never used a spirit level.
Been on Aires where we have had to use the front drop down bed because rear beds were at too much of an angle to sleep, fridge still worked ok.
The older fridges were more of a problem.

Draw a line representing horizontal. Draw another at 6 deg to it. The further you are from the junction of the lines the greater the gap between them. Like this:

To level a van length A-B you need to lift the lowest end the distance between the upper and lower lines at point B. Likewise for a van length A-C where you need to lift the distance between the upper and lower lines at point C. I have no idea what angle I've drawn :D.

6 degrees is a slope of about 1 in 10.
A MH with a wheelbase of 3 metres will need the wheels raised by 300 mm to make it level.
A MH with a wheelbase of 6 metres will need the wheels raised by 600 mm to make it level.

But it’s still 6 degrees :)

You can’t re write physics :rofl:

He is not rewriting physics he is applying it or rather applying maths. For any given slope the longer the distance between the jacks the longer the jack on the lower side will have to extend to get level. It is simple trigonometry
 
6 degrees is 6 degrees short van or long van, it just comes down to wedges a wedge of yellow plastic or a wedge of cash your choice, and as @cliffandger says its not just about level anyway.

I understand that but it’s not what was said.
In brief it said a short van is less of an issue at 6 degrees than a long van.

Or that’s the way I and many others did :)

It’s obvious you require a longer lifting mechanism from the point you are rotating from the further you get from said point :)

In general terms he is correct. The longer the van, or more usually, its wheelbase, the further apart the jacks will be.
 
In a longer van you will need longer jacks, of course. But even in a 5m van the fridge will still shut on your head, the pans will slide off the cooker and the children will roll out of bed. It’s no easier to live on a slant in a shorter van.

That's correct. It is just much easier to level a shorter van.

I meant less of an issue to level and thus less in need of hydraulics than a longer van. We were (I thought) discussing the need for levelling jacks on such a short vehicle.:)
 
Don't intend getting jack's still getting in the ear from spending 7 grand on air suspension, might have helped if I have asked permission first.:ROFLMAO:

9 /10 with the air we can get level it is nice not to have the fridge door or draws opening & closing on their own. Nice but not essential doesn't bother us too much if we are on a slope.

If staying more than one or two nights not something we do often I might get the ramps out if we can't get level, if I can be bothered. Obviously if the beer is in danger of falling off the table I will.:)

And don’t forget that Hydraulic jacks are not “just” for levelling.

The reasons we went for leveling is with the short overhang at the back there is less of a cantilever effect to pull the back end down so the level can be further off, those of you with longer vans have the advantage or disadvantage depending on how you look at it! Of around 200kg's of extra weight on the back for every metre added over 6m of course this comes off your payload, and with a garage on the back this can accomodate further weighty items to help compress the rear, not a problem so much if you do not intend to stay below 3500 kg, plus finding somewhere to store large ramps can be a problem while travelling.

And you just fancied it;)

I make up all sorts of reasons for having it but the overriding one was plain and simple “I wanted it” so I had it, spoiled brat that I am.

I can't sleep downhill, i.e. with my head lower than my feet so I need my bed to be level or a bit high at the pillow end. No, I can't sleep the other way around because if I did there wouldn't be anywhere to rest my ashtray, pork scratchings and pint of Stella.
 
If i had the money i would defoe get the system fitted, We were away last week and a motorhome had axel stands would that be just to stop it rocking? Any movement or wind in our motorhome creates loads of rocking and wakes me up or kids.
 
If the self levelling jacks are up for long periods do you have to spray the rams to help prevent any rust etc ? Just being nosey.

I think the instructions say silicone spray actually but I do wipe ours down with an oily rag now and again.
