The early marlon Xplores seemed to all have frowny faces when the sides were extended. The extrusions were too weak for the weight I guess. New ones seem better.
I have one that is 4 seasons use on it now. The ramp is a bit flimsy in comparison to the old marathon I had it rattles and can be heard in the cab. The LED lights all quit and had to be replaced. Chinese quality. The mounting pads are ok but a bit of a pain in the ass putting deck in and out. You have to be careful with the way they have the plate you drill thru to bolt in orientated that you don't hit the pinch seam.
Overall not a bad deck but overpriced in my opinion.
