Trailer of GOLD BARS??? How much does that thing weight? Wifey and I went to MD-2013, 2 Up, Trailer 350lbs and got 39 MPG there and back. Sorry no Major HILLS between Don's and my Place. I AVOIDED the HighWays so no 70mph... more like 55 to 65-ish. Joe losing only a few MPG sounds right... also my tralier looks SCARY when hitting potholes at 70 mph.
