Thanks fellows for all the responses and your suggestions. I have pulled 5th wheels for may years both with and without leveling systems but this is my first Class C coach and was just wondering how others went about leveling theirs.
Pfflyer, when I pull onto a site that appears to be 3-4 inches or more low on one side or on one end, I use blocks or boards to bring that side or end of coach up to a reasonable level before deploying my jack system. I don't won't a wheel or wheels to be hanging in mid air or one jack or more reaching its full extension without contacting the ground or jack pad. After I am on a reasonable level, I deploy my jacks onto jack pads. Like hopper stated, I will place as many pads under a jack as needed.
My main interest was what folks use under their dual wheels and if they used one for each separate tire or one pad for both tires, as both need support. Either way would work, just wondering as one pad for both wheels would be quite a bit larger and more difficult to store.
Thanks again folks
