Planning a trip

Got myself a 6 month break (sabbatical) coming up in the next year or so.

I want to do plenty of flying so rather than do a coast to coast I figured
on trying to fly and land in each State/county in the contiguous US.

Living in Europe, I would probable buy a plane, fly it for the duration and
sell it when done.

Welcome any thoughts on best plane for the mission, best time of year /
route to capitalise on the weather re most flyable days.

Speed is not a major requirement but with mountains to negotiate performance
could be an issue unless the mountains can be neutralised.

Would also want to rig up a TV camera to record the trip. That would be
covered by someone else as it would be necessary to have camera remote
controls on near control column, yoke.
