I guess it depends on what you are used to. If you came from driving an SUV then a 35' motor home will be much different. I have been a trucker most of my working life so the motor home in my signature is easy. I did have the alignment done not long after we bought the rig new. I have not done any other mods to affect handling and don't need to. I think the relationship between wheelbase and rear overhang makes a lot of difference in handling.
Yeah, If I had mucho money I would have a nice DP but the rig we have suits our needs and it fits the rv space we have reserved for the winter so whatever works for you?? :D
