Here is a comparison in travel comfort that might interest some...As far as hombuilts go I have flown in an RV-7 (round trip) from Phoenix to OshKosh
and I have made the trip from Phoenix to Boise (round trip) in a Kitfox IV three times. The RV certainly wins as a time machine in speed, but the Kitfox took the comfort prize every time. The design of the seats have been well thought out and designed for the KF.
