1 ton flat beds come with an 8' x 10' bed.
1.5 LWB and 2 tons will have an 8' x 13.5' bed.
If you can find a 46 LWB school bus the have about 195"
wheel base.

Thing with these trucks is that they ride hard, noisy, poor
gas mileage, cruising speed about 40 to 45 MPH. So unless
these things are ok to your wife she may not find using
one of those Art Deco's practical.

I have to admit that I have thought about how much fun it
would be to turn an old truck into an RV and travel across
the country.

Though the Art Deco's are one beautiful looking truck.
Yesterday, Forest Gump was on TV and when he gets on the
school bus for the first time is was an Art Deco Chevrolet
school bus. Jeffrey
