Lots of good advise. I would get Coach net incase You have a problem and need to be towed or have a tier changed ect.
I have had a few miner problems on this trip but nothing that was major. I had to change a slid controller board but called ahead and had it waiting when I got to the next stop. I had the water valve on the toilet go bad and caused a little flood when I forgot to shut off the water pump after a stop. Had the P trap under the sink vibrate loose after some really rough roads. All I had to do was reinstall it and tighten it again. I had several other miner things to fix but I don't worry about it I just do it. I just checked We are 4300 miles into this trip about half way.
