Gman, first off, there has to be a very happy family in your truck/camper combo. Also you have made a difficult decision putting the main household repairs first. Kudos to you.
Starting over for me would involve my wife and her needs as well since we are planning on many trips together. I still would want a larger camper with slides. I've done backpacking, tenting etc and this is our choice. I've tried to minimize costs by shopping out of state. The camper came from Oregon and I looked for a year finding my Ram truck in Indiana. Vehicle taxes are unavoidable but I think I saved some dollars. When you start looking, be prepared to jump. Good luck!
