Hey all, im new here. some one told me you guys might be able to help. Im looking for a set of 6 (dually) wheels that will fit my m300 chassis. I currently have tube type but need tubeless. Reason being that i am airing them down for the beach and the tube type might pinch, or spin on the rim.

also, what rims will fit my 72... can i take the 8 lug hd rims off a newer (90s) ram truck? will they fit? what rims are compatible? this is a motorhome?
