I need some help quick - got a job offer coming-need advice

I would say research RV parks in the area to see if they even offer seasonal/full time RVing. Give them a call if your questions aren't answered on their website.

As far as size goes, think about that idea of getting a small trailer. You'll be living in it every day for 2 years. If more space is what you need, for $20k you could get a slightly used bigger trailer.

Do you plan on RVing more or full time RVing when you do retire? If so, do you buy your retirement rig now?
