Changed my order to the XL on the 170, my 144 Chassis was delayed and 170 was available at the port, I think we will appreciate the additional space!He's building a different version on the MB 170 3500 now. Either with a twin bed setup in the back, similar to the EKKO or a larger platform. I haven't seen the floor layout, but a few of his recent short videos on YT show the larger panels being laid out.
