I thought this would seem fitting... a couple of weeks ago I hauled my buddies boat behind my 5er down to Pueblo. I won't make any Ford jokes, because my buddy owns a 6.0 PSD and a 30 ft 5er and claimed he was too long to haul the boat behind his 5er. I estimate I was around 21,000lbs total between the truck, 5er and boat and right around 71 feet long. What a train!! Got 10.5mpg average going 65-70mph. Not bad at all!! Hopefully the pic shows up...
