Couldn't agree more with the above posts. Especially the comments regarding speed. I know - everyone is in a HURRY! When I drove OTR in a semi, I used to get impatient with "the old guy in the MH with nowhere to be and all day to get there". Now that the DW and I are retired WE are the rolling road block holding up traffic. Putting aside the fact that the west coast states require you to travel 55 mph when towing, I try to keep our speed at 60 mph. The truck seems to like it there. Besides - at 55 mph, our average daily mileage of +/- 375 miles takes 6.8 hrs compared to 5.36 hrs @70 mph. I've lost count of how many times we are passed (like we are up on jacks) only to pass them by at a rest area further up the road. To each their own - but - why not slow down and enjoy the trip? Plus the added benefit of saving a little of your truck and your tires for tomorrow. Just sayin"
