Hello,
Thought I would share with you how we purchased our camper. We started out the same way you are, not really knowing what was out there and what all the options were etc. There were several things we did that really helped us. The 1st thing we did is made three lists. The 1st list was what we knew we absolutly needed on the camper (ie DSI water heater, A/C etc). The 2nd list was what we would like, but could live without. The 3rd list was things we did not like at all (believe me, you will find them).
The next thing that we did was look at our tow vehicle and what towing capacity we had (this is extremely important). If you don't know this, the dealers are still going to say, yep, you can tow it. Guess what, new transmissions are not cheap!! KNOW THIS!!
Then once we knew what we could comfortably tow weight wise, we started looking at Manufacturer websites and the different floor plans. Most of these sites allow you to download product brochures that you can print out. Remember the lists you made earlier, the product brochures will match up with your wants and needs. At this point we narrowed down to floorplans and manufacturers. In conjunction with this, I got on every camping forum I could find, rv.net, hybridexplorer.com, many many more...just google rv forum. I would read as many posts I could find that dealt with the models and mfr's I was interested in and would post questions I had. You will be surprised what you will find out. You can even post question about particular dealers and you can find out a lot about them!!
After I was armed with this info, we planed on hitting as many RV shows we could find. Traveling as far as 150 miles one way. This paid off huge!! If you can hit a big show (ie: Chicago, Indianapolis) you will find not only several competing dealers there, but also manufacturers there (yes actual mfr's that you can speak to). We loved this. we were able to see the exact floor plans we had put on our list and then walk to the next one and compare. We began talking to the different dealers and our questions changed from what can you tell me about this unit, to why should I buy this from you when I can buy this one from him. Oh boy did that change the ball game!! Especially when the dealer watches you go from him to his competitor!!
We went into the shows with no purchase in mind. Just fact finding. Once we found the right unit and the right dealer, we then contacted the dealer and started the purchase process. we were told the prices we were told at the show were only show specials. When they said that, we didn't even speak and got right up and headed to the door. Funny how they changed their tune!!
Point is, take your time!! Make lists of wants, needs and nice to have's. Spend time on the internet. Hit the RV shows and have fun at those!! Don't think you have to jump at the 1st deal that comes around! If you can narrow it down to a couple different choices and then try to deal with those, you will get a good deal. If you go in and say, I want only this model no matter what, you won't get a good deal!
Financing, look at what they offer. Watch out for the interest rates! Also make sure there is no penalty to pay off early. We ended up with a better deal financing with our local bank at a cheaper interest rate for a short time. Yes, our monthly payment was higher, but we saved over the course of the loan on interest.
Good Luck and happy camping!!
