some have done that but too proud to admit the mistake.
All the RV units that use chassis from suppliers run 4.11 /4.55 using the
same wheel and tire.GM , Ford and Chrysler know more than us

Are you referring to making a mistake of lowering final drive ratio on the GMC?
As far as box RVs - yes, they run a much higher final drive ratios, but that it because output shaft on transmission comes out at a very different speed from what we have going on in our GMCs
