460ci is my favorite motor for a gasser and I have owned 454ci, Ford v-10 and the 460. I loved having a motorhome at the track. A clean bathroom at your disposal, a stocked fridge and some A/c make it worthwhile. If you are in it for the long haul diesel is the way to go. Just testing the waters as long as you buy it right someone is always looking for one when/if you wish to upgrade. IMO, the generator is second most important piece of equipment so make sure it is up to snuff!!
