Attended a Coachmen Rally in the Florida Keys back a couple years, so Mid Michigan to Key West, with a side trip thru Alabama was just over 4000 miles. 2010 was a trip to Custer SD at a little over 3000 miles.
I have also taken the trip up to Copper Harbor/FT. Wilkens state park. Gotta love green because once you cross the bridge you see alot of it. Would love to take the trip again. Only problem road wise I encountered was crossing the bridge in Houghton/Hancock. Highway actually turns left immediately after the bridge and does a switch back kind of thing up the hill ( pretty...no freakin' steep hill!). I naturally not paying attention went straight. Don't know the grade but it was an angle 35-40 degrees. Steep enough that the map book slid off the dash.
Had a 99 powerstroke and our 37' prospera at the time. That old powerstroke was sure beggin' for mercy! Couldn't muster much over 15mph. So yes, remember to turn left over the bridge!
