Personally I don't mind running slow up the hills. It is more of a safety issue. When you are going 20 miles less than posted speed limits it can be dangerous. And I worry about the engine being under that much stress if it is a long climb. Any word on alpine gears?

That's just the way stock busses run. Unless you want to go to big engines to correct the problem. Come to Nacogdoches and I will let you drive the bone stock 60 panel with stock tires and a stock 40 and when you get back in yours you will think you are driving a full blown 100 hp engine.

It runs great in the realitively flat stretchs but really doesn't power much up a hill. I live in W Austin and there are hills between me and any where I go. I have the stock 14s, would smaller tires help? Maybe the answer if alpine gears? If so how much would performance suffer on flat ground. Jeff
