You could run up several thousand dollars in spare parts only to have something unexpected go wrong. Some plumbing bits and some eternabond tape will stop most water leaks which is the biggest danger to your rig. Most any other problem is just an inconvenience.
70 miles is only an hour and a half or so drive if you need something major. Even then the dealer might have to order it anyway. Amazon Prime is just a day away and you don’t have to drive 70 miles and pay inflated dealer prices.
