im interested in doing a dually conversion on my 1978 dodge d-200 im looking at doin a 3in offset inner wheel and then a 4in wheel spacer then my stock no offset rim do any of you know about doing this as i have just had this idea and ive done a bunch of reasearch for it and i can do it all for 150 dollars just wondering yalls opinion on this

 

The camper I bought to get my 440 came with a dually rear. Thought about putting it in but all you'd gain is the fact that you'd have to buy two more tires lol

 

no but im talkin like addin leafes and doin the wheel spacers and building somw of my own fenders just for some more weight and the stability a dually brings pulling a trailer
