I'm asking for opinions

The cummins would pull the trailer and its a 12 valve with a standard so it should get mileage in the high teens to low twenties. Also im a big diesel fan. Plus if your loosing a dually you should replace it with one if you used it alot. Another option is getting on an inaurance website such as tra auctions or copart and buying a wrecked vehicle that only needs cosmetic work since you can get newer stuff fairlt cheap depending on what you want. V8 chargers and challengers are out of the 5,000 range though because they always get bid way to high. Also foreign countries bid on some so if you see abu dabi bidding just give up lol. What im sayin is you might a newer dually to replace that one pretty cheap and throw some parts on it and your good to go
