My advice: it's like buying a used car, but often worse. The "MSRP" and "Invoice" etc numbers mean absolutely nothing as far as I can tell. They're completely made up by the dealer or the manufacturer or both. The best thing to do is to compare the same model nationally - if you can get it somewhere else for $1k cheaper, you're probably good and in the ballpark. If you can get it one state over for $10k cheaper, you're being ripped off. Also, same as a used car, don't think about it too much. It will make you crazy. Get a reasonably good deal, and never think about it again, just have fun! Money comes and money goes, but life is fast and short, and you don't want buyer's remorse to hang over every camping trip. That's my personal advice.
