Denny I moved my seat 3 " higher like you suggested but even though I'm only 5"10" my head hit the top. I'm going to take the speakers from behind my seat and then cut my bench seat from back to front about 3" to see if I can pick up some leg room. That will still give enough seat for comfort. Last year my wife and I drove to Pa. for a show and I had to stop about every 60 miles just to get my leg working again. The seat that was put into my truck came from Dodge Caravan so its big to start with.
