Height is less of an issue as having the drivers seat as far back as it can go and his knees still touching the dash .... that is the big issue we have not been able to get around. Anyone have luck with an RV that has a drivers seat such that a man with long legs can drive comfortably? He is only 6'3" but has very long arms/legs so the space between seat and dash is an issue in RV's.... We are shopping for like new under 30 foot diesel.
