We encountered a bunch of problems like that last year - but we were on the road!
It started with a blow-out on a very hot day. While changing the tire we discovered 2 of 3 bolts were missing from a crosspiece underneath the trailer frame. Once we got to our destination we discovered we had no hot water. During the course of clearing the check valve, our little flashlight rolled off the top of the battery
box (admittedly a stupid place to lay it!); it took us a couple hours to fish it out...
Anyway, that trip presented a series of challenges, but we overcame them. It made the trip very satisfying, I must say.
So, hang in there. You'll work through all the issues, one by one. And when you're ready to get going again, you'll appreciate it all the more!!
