I would recommend that you reconsider the length of the coach. I have talked to a number of full timers (since I was thinking about doing that) and I never heard that the coach was too big. However, I did talk to people that wished they had purchased a larger one. After much research, I concluded that if you were going to full time, it was best to look at 38 foot or better. If you are single, you may be happy with something smaller. This is not to say there are not people full timing in smaller rigs. However, after talking to a bunch of folks, most want something bigger.
I would suggest that you talk to full timers. Post a message in the full time forum. Talk to people. Do a lot of soul searching. It is expensive to buy and sell so do your best to get it right the first time.
