The more you shop, the more confused you will be....then you will walk in a M/H and "click" you will love it. Many years ago we started out with a 20' Class C...overhead bunk, rear bed and dining table made a bed...we had 2, 4 and 6 year olds and it was a little close, but they loved the overhead....then a 23' C and now a 34'A. The kids are grown and gone but we had a ball in the smaller units. I would have liked a larger one then, but "it is hell being poor".....ha ha
Figure 45K for the MH and another 5K for fixup stuff....I just bought six 19.5 tires installed for $3,000 to give you an idea.
Unless you empty your kitchen, you will need silverware, pots and pans, toaster, coffee maker....ete...a duplicate of your kitchen cooking items...cups, plates...grill, ladder, tools....you get the idea....this is not the "buyers" season, but it will be in six months. Enjoy
