How many of us are there? Owners of Dodge based RV's?

I put 16's on the 77 Dodge Jamboree and it works just fine... worring over tire diameter is something that a racer would worry about. In the real world, it ain't no biggie... and good tires are affordable. You can go to the trouble of 19's if you want, but I found rims, and tires and spent less than $800...
