1st time long distance trip need advice

Somebody finally said it, but I'll underscore. Get a copy of Next Exit. We keep a hard copy right between the pilot and navigator. If anything goes awry with plan A, you can use that handy reference to see place that can handle your rig. I just bought the newest edition on Amazon for a friend, like $25 ish. I always plan my trips out. I have diverted from plan, but i try to keep it reasonable to begin with. I scope out gas stops in advance so I know where and when I'm stopping. (yes, it can change=Next Exit) Same for overnight. I prefer NOT to stay in parking lots, especially when towing. Many do tho.
