Hitman, When my dually wore out (>300000 mi.) I went looking for another one the problem was that new they were ~$40K And I found a used low Milage Moter home for $15K it has an 8.1 vortec with an over drive trans.
The previous owner had pulled a 24' tag with a 3500# car in it. Since I was going to pull a 32' 7000# tag with it I purchased a trailer toad to keep the tongue weight off the motor home.
Pros:
AC at the track 24 hrs a day for ~$10-15 per day
Another generator
Heat
Microwave stove shower & potty TV
Confortable place to sleep with out the hassle of hotel rooms
You can have a beer or two after the races if your not driving home.
Cons:
Tows almost as well as the dually simular 6-8 MPG@70-75 does not stop as well.
The parts for the chassis can be expensive and harder to find
You gotta empty the black and grey water tanks
There is a lot more maintenance on the RV tanks to empty and fill, batteries,carpets and seats to clean, refrigerator to keep stocked and plugged in,another generator to maintain etc it takes us as much time to prep the RV as it does the race car and trailer but for me the comfort and convenience is worth the hassle
Oh one more con: they start racing stockers every day at the U.S. Nationals at Indy at 7:00 so if your sleeping at the track your not going to sleep in.
