Welcome Paul,
This is a great place to learn about what is available. Just one bit of advice, when you decide what you are looking for, you need to be diligent and be ready to act as soon as you find it. Be ready to travel to check out anything you are interested in, and be ready to close the deal quickly - have money in hand and ready. These trailers sell quite quickly, especially as we get closer to spring.
Good luck, and make sure to ask any questions. Some folks will point you to do a search if it is a common question, and that is a good idea, but don't be afraid to ask - some of us don't mind discussing the same topics repeatedly.
When doing a search, click on the "Search" option at the top of the page, then enter your search terms in the "Google Custom Search" box at the bottom of the drop down. This will give you the best results.
Good luck with your shopping.
