I just put a set of the Dodge diamond plate running boards on... they must have upgraded them as I weigh about 190 & the back boards don't flex at all that I can tell!
My boards match fine... but the first set of rears the dealer had to reorder because they found the box had been dented in transit & they said that one board was scratched... . so I did my fronts first and rears later.
Paid somewhere in the area of $500-600 total from the dealer for front & backs for the 04. 5 dually, including the diamond plate splash guards (I think the rears are included in the kit).
You have to drill a couple of holes and having an angle drill & a short bit will help. Took a couple of hours per side, including painting the holes so they won't rust later, but I'm really slow.
The instructions were minimal, but the brackets are strong & well made & I think that the boards look great. Sure makes a difference reaching in the back of the truck & so far no stone chips!
I did it by myself, bad back and all... . first time I have ever installed running boards & although I was really slow, the labor was free & I didn't make any mistakes!!!
All in all, if you like the looks, I think they are a pretty good set of boards. However you might open the boxes & check them before taking delivery, as they are imported & maybe the quality control isn't the best, mine were fine though... Good luck with whatever you choose!
