I'm at the same point you are. I originally built my truggy with the intent to be somewhat street legal, capable and get me back on the trail ASAP. Just wanted it to be built once, small mods as needed and stay reliable, meanwhile collect parts and build a buggy. I like the cab to keep the weather out(not so much since the tube doors), but also being on the borderline of legal midget, the cab hinders me from seeing well. The whole cab thing is cool, but a wide open feel of a buggy is wayyy more cool.
Actually cutting the roof and exo off mine tomorrow after work and redoing some things. Link the back of yours, cut the sheet metal off and add tube, way simpler than starting over from scratch.
And Bent Fab does have some really cool chassis, that are really simple and clean.
