Dodge motors
Nick,
If you take your shoe off, turn it upside down while holding it with one hand and tap the heel with the other hand, you can get most of the sand out. :laugh:
On the subject of your Dodge. If it is well tuned and you drive about 60 MPH I suspect that you will get about 10 MPG. It will be VERY sensitive to speed. Five MPH slower will do better, 5 MPH faster will do worse.
In addition to my motorhome, I have a '72 Ford pickup with an 11.5' slidein camper. It is my previous RV. I kept it because it ain't worth sellin' My gross weight is about 9K lbs. I get about 12 MPG at 55 and 9.5 MPG at 65. That 10 MPH cost be +20% in fuel. Your Dodge will do about the same.
