We sold our '99 American Dream (Cummins 330 w/ Allison 6-spd on a Spartan MountainMaster chassis) and are looking to get another motorhome. We are considering going to a gas rig but......everyone we've driven seem to have a lot of side-to-side sway, as though it's top-heavy. In our coach we didn't have much of that - probably due to the large air-bags.? Will we ever be happy with anything else but a big diesel on the raised rail-type chassis ??? The gas engine part doesn't bother me, and the engine being up front doesn't either - it's mostly the sway- the rocking, due to wind or 18-wheelers, etc.? The gas rigs we've driven have been a '04 37' HR Vacationeer, and a Monaco La Palma.? Does the ANTI-SWAY bars really do that much for the swaying, or is it more 'snake oil'?? The gas rigs are much more affordable for us, but don't want to make a massive mistake.? If anyone has ever gone through what we're going through please let us know your thoughts or ideas.? Thanks?
