Sorry to hear of your engine issues.
I wouldn't be in too big of a hurry to give up the full time traveling life, unless you were getting close to the end anyway.
First of all, if you are even considering purchasing a sticknbrick that means you have funds set aside and a decent income. If you didn't obviously you wouldn't be thinking of buying in such an inflated housing market that exists currently. So if you are financially okay then there are other options maybe to consider.
As someone suggested you could live in your MH until the repair parts were at the shop, then maybe you would only be displaced for a week or two. Another option could be move in with friends or family, or even an extended road trip in your toad visiting.
Good luck with whatever you decide and let us know.
