NADA

Also if you are looking at a dealership, consider all the fees they will be adding, documentation of $399, PDI $500, and even dealer prep of between $700 and $1000. I even saw one large dealer in Ashland Va that had a transportation cost line on a used trailer they took in trade. With a private party sale, all those supposed cost magically *go away*.
Your real cost is likely a lot more than you think.

The dealer is going to try to make as much profit as possible,
Start with a low offer and negotiate the price.

The 'starter kit' will probably be lower quality items to make you think you're getting a good deal.

If you are new to RV's, hire an independant RV Tech to inspect the unit you are seriously considering. Or, if you know someone who is familiar with RV's, maybe they can check it for you.
The cost for an inspection will be well spent.

Do not rely on the dealers inspection. And, get everything in writing.
Also, do not put money down until or sign any agreements until the unit is up to your standards.
Many dealers will tell you to bring the unit back after you make the purchase and they will fix any problems.
The problems should be fixed before you buy.

If possible, take your time. Don't rush into a purchase. Ask lots of questions on the forum. Someone will have an answer.

google the rv see what there really selling for. nada is just a very ruff idea.
