btw, my current car is a 2005 Honda Odyssey. Has everything I need except towing ability and MPG. It's probably just a little larger than we need day to day but great for carpooling. Any camper I buy will be 2200 pounds or less, ideally less than 2000, because I don't feel comfortable hauling more than that.
You'll only find the weights you list in a small pup and even then you'll find it hard to stay that low once loaded up. You should be able to tow under 3k comfortably with your Oddysey. If it's in good shape Id keep it and get a pop-up. Even if it's not the best mpg, you'll pay a lot more buying a new vehicle.
Want a TT or hybrid and a vehicle with 3 rows of seats and you're into a mid to large SUV. Some mid size SUVs will have 3 rows and can tow 5k (4Runner, Durango etc) but they have limits too. Full size TTs and hybrids will exceed 4000lbs loaded and then you have the drag from the frontal area to consider as well. For those reason a V8 would be the better choice but then you can throw the mpg out the window.
