mkirsch's summary was exactly spot on.
Fully loaded with 2 years of stuff, your camper will easily weigh 4500#. Yeah, you can do that on a single rear wheel truck if you are going on a weekend jaunt. To drive across country for 2 years? No way.
Truly, truly, you need a dually.
I realize you are on the opposite side of the country. But, my experience here in Seattle buying used stuff like cars and boats is to avoid the 2004, 2005, 2006 models.
In that time period "real estate only goes up in value" and too many people used their homes as ATM machines and bought too many toys at TOO HIGH A PRICE. The high prices they paid in are still reflected in the resale price today. Often you can find a newer 2009 or so for the same price since the manufacturers where giving away stuff then.
Your idea to avoid towing the Jeep with the Class B is right on. We RVed full time for two years in a 38 foot diesel pusher with a Jeep in tow. Heck, there were plenty of small towns we couldn't even stop in since there was no place to park. Also, don't ever miss your turn unless you want to drive 17 miles out of your way to make a U turn.
