Question for the electricians out there.

I am insulating and dry-walling my garage. Before I close up the ceiling I am thinking of running some conduit to make things easier in the near future when I have both a 50 amp circuit to plug the 5th wheel into and a portable generator (7Kw) plug-in installed on the far side of the garage. I want to make sure I put in a large enough conduit for the size wires I will need.

Breaker box = Point A
Transfer switch = Point B
Box on far side of garage where Generator would be plugged in = Point C
Post to plug 50 Amp 5th wheel in = Point D

A to B = 8 feet
B to C = 38 feet - This is the section where the conduit will be. 28 feet across the ceiling and approximately 5 feet down each end.
C to D = 25 feet

The RV 50 amp is a 4 wire. That and the wires from the generator to the transfer switch would share the conduit. B to C.

What size conduit should I put in to make an easy install later?
