Help! Need advice! New to RVing

I hope you have some towing experience already. If not that's a huge trailer to learn on. I don't know if you have a truck to pull it yet either but you will be solidly in diesel dually territory with a trailer that size.
No matter what you ask the dealer just remember their main objective is to get you to buy the trailer. I find that I often know more about a product than the salesman because I've already researched it.
