How many of us are there? Owners of Dodge based RV's?

Had 2 great campers like this: 73 Glading del Ray 18' and 73 Tioga 21'. Both had no grey water tank but I put one in the Tioga. Both 360 cid 2bbl engines, never had any issue. Went up and down the east coast for many years. Good aluminium roofs and way more solid cab over construction then more modern ones that I have had. Let me know if any one needs to put in a grey water tank....
