I had alot of time over the holiday week to read other peoples builds, mostly on ADVRider and Expedition Portal.
Here's a fairly accurate sketch of the bus, left is front/right is rear.
So the pic shows (left to right):
-front passenger doors at the top left (drivers seat bottom left, not shown)
-half wall keeping kids out of the stairwell
-rear facing benches (left & right sides of bus)
-forward facing benches (l & r sides of bus)
-(3) wheel chocks
-rear wheel wells
-gas fill tube (bottom of pic)
-rear heater (bottom right of pic)
Starting to think I may put in a divider wall between the "garage" and passengers, to seal out gas fumes and road noises during long trips. Also thinking I may ditch 2 of the 4 benches, front ones facing the rear of the bus & the half wall. Then put a van swivel bucket by the stair on the right side and just have seating for 6 adults. 9 adults is alot and there is a lack of space, might even add a 12volt powered Ice Chest or an RV 12v/120v Fridge behind the driver.
