Eldondo, I think we all have a little bit of fear and anxiety at first before leaving on a trip. I have to admit I go through a some of that myself thinking about 'what if....'
Then, I have to say that it all goes away once I turn the key and start rolling. Sure, things can happen, break, need servicing, etc., it's just the nature of the beast. I have insurance, road side assistance, redundant systems (for house), so I just try to live life to the fullest. It's all in the adventure!
You don't have your RV listed in your sig, maybe your RV is too big?
Safe travels,
MM.
