V-Dub - I'm new to the forum from Olathe as well! We have a bumper pull toy hauler, and I will echo the comments above. Once you get started, there's hardly room for the toys with all the chairs and tables and everything else you pack in there. The same rules apply as your house, your stuff will expand to fill all available space LOL.
As far as the generator goes - we ended up dry camping a LOT more than we thought we would. Remember that if you are going on a long trip, you can easily overnight for free in a Wal-Mart parking lot. Your wife (and kids if you have them) will be MUCH happier if you have a generator!
I just bought a Class A motorhome last week. I have a Diesel TV (2011 Ford F-250) for sale in the classifieds, you might check it out! I live by Heritage Park and the airport, 159th & Pflumm.
