Oh yes, Entegra, forgot to add them to my post, have been looking at them too.
I dont believe I wrote that we needed 45'.. Although I would like the space.
Our 5er is about 42' and we tow it with a 4 door Duramax, I think we end up close to 59' in length and there is all but maybe 1 or 2 parks we stayed at last year where I think we would be able to fit with a MH Stacker combo. We havnt boondocked or went to places where accessibility is borderline an issue. In some cases if we stayed for awhile I may not even be opposed to getting the spot next to us and parking the stacker there if the spots arent long enough for both. Some places this would become pricey but In some places we have stayed it would still be reasonable.
