major upgrade Have not missed the dmax one bit. I do miss the 4 door cab though, but Im extremely happy with my choice. Way better mileage too!

Since Im no longer a duralemon owner Im unsubscribing. Take care all!

not pointing fingers but i think some people have a bad expirience with something and they then consider it junk. in my opinion all things mechanical and electrical will let you down at some point in time. some llys had headgasket failures due to an early bad design of crimped gaskets instead of riveted gaskets once fixed your good to go. i almost wonder if the gentleman above would think his dodge was junk if his lift pump failed and wiped the inj pump?? if he had no knowledge of that issue.. as stated above everything and anything has some sort of issues

I have owned both had an ip go bad and lift pump failure, plus a handfull of trannys in the dodge, the dmaxs that I have owned so far I have had to change the oil and fuel filters that's about it.
