We just bought our SP295 this month. We saw one at a local dealer and fell in love with everything about it. We couldn't get over how much thought went into the design and layout of the floor plan. The problem that we had was that since it's such a popular model, the local dealer wouldn't deal on it at all. They wouldn't even throw in the hitch. I don't know what price you've been quoted, or where you live, but after doing a web search we wound up driving 12 hours from Mississippi up to Hamilton, Ohio to pick ours up. We saved several thousand dollars by buying out of state and the hitch was thrown in as well. Check out this link
if you're interested.
We haven't used a generator with ours either, but we pull it with an '03 F-150 Supercab 4X4 with the 5.4 L and it pulls fantastic. The only issue we had on the way home from picking it up was walking back out to the truck from a lunch stop I noticed somehow or another birds had managed to build a nest between the back of my trans cooler and the front of the radiator
. I have no idea how long it had been there, but I very quickly removed it...
