Noticed your comments ref AutoBruise and agree as I had one for years.Level up every time, no particular reason just do it. What surprises me is the CS site I use near Penrith, all of the five hardstanding are level. I just park up and check with my level and to date have never had to use my ramps.
Numerous motorhomes park up and use levelling blocks. I would say nearly all Autocruise c class use them predominantly on the front end. Are they made with the front end low ?
Yes, it would be at that length. However, I thought the longest wheelbase of VW LT 2.8TDi was "Super Long: 3650mm" which is less than 144 inches. Has yours been stretched?

Not actually checked how true the van actually is when on level ground. That would be interesting to know - I think I will take a long level and check it out. I would assume that in all non-self leveling vans, the angles will vary in use depending on fresh and waste water levels and locations as well?
If you need a spirit level or an app, you are getting carried away!
If a coffee mug slides across the table, it won't do. Otherwise, it's fine as far as I'm concerned.
I hate it when the sink won't drain properly and I have to use a squeegee or similar to get washing-up dregs down the plughole. I also don't like to sleep "head down". So I'll spend a few seconds with a phone on my dash getting the van reasonably level. As I wrote upthread, within a couple of inches side-to-side and half a foot front-to-back is good enough -- and that app tells me when I've done that before I get out of the driving seat and without checking that coffee mugs don't slide across the table!
