Mine is the front engine model. I like it so far but am still working on the conversion. I kind of wish I had a rear engine as there is so little useable space under it for tanks etc. I have really struggled with how to mount everything under the bus. But I am happy with the turn radius and how much space is inside. Ceiling height is good. The bus is sturdy. It goes down the road well.
I am a bit puzzled as to why you can't find enough space to mount stuff under the floor of the bus.
You have almost the whole skirt area on both sides between the axles and all of the area behind the rear axle. You can easily build stuff to at least the level of the bottom of the skirt without worrying about dragging anything off. You could easily go another six or eight inches and still not worry if you were careful on entering and leaving curb cuts. You could build down 12" from behind the axle to about halfway to the bumper without worrying as well.
That much space is a lot of space. And except for making sure you can still access or drop the fuel tank all of the space behind the rear axle from side to side could be used, particularly if you have your exhaust leave out the side just in front of the rear axle.
