RE: YOUR LONGEST ROAD TRIP?
the longest I have ever driven straight through would have to be Iowa to englishtown new jersey 1115 miles for the Superford Nationals, we did it several times back in the 90s but that was with a toterhome, twin 200 gallon diesel tanks, on board bathroom and galley so we didn't even pull over to switch drivers half the time, just a quick swap and motor on. My uncle has since sold his but is looking for another stacker style one so he can take two cars without having to lug a trailer.
Some guys might not know what a toterhome is so here is a picture of a nice one that was for sale here a month or two ago, this one just had a standard single 16 foot garage on the back however.
