If it's only $4000 for new, then it would be a no brainer for me. Forest River is a decent brand. Like most RV manufacturers of *ENTRY* level trailers, they share the same engineering technology.
Your getting at least a one year warranty in which any bugs in the rig can be fixed. Add to that, the value of the new trailer will be higher if and when you are ready to trade it in or sell it. On a used unit a bad leak alone could cost you a few thousand to fix. Like you mentioned, the tires will be brand new. You will also have a choice of floor plans. Hopefully, the dealer will be close to home in case future repairs are needed.
