I haven't done a lot of driving in the old beast as it needed a few minor things like engine, front bearings, gas tanks, exhaust...

Any way, I installed a tach a while ago, and yesterday took it out for a spin.

So I noticed that at 60, by the speedo, I was running just under 2500 rpm. I was thinking 2450.

According to Jims chart thats a 3.42 final drive ratio??

The speedo is really close, or slow if anything.
I do not see a ratio adaptor on the speedo cable.

This coach was redone in 2002 and was set up for towing with a big honkin hitch and an electric brake controller.

Do I rally have a 3.42??
