I believe this2003 isuzu npr crew cab has the 5.2 4 cylinder turbo diesel in it and was wondering if they are ok to pull a 7x14 dump. Fully loaded the trailer can be pretty heavy. I plan on using this truck for a chipper down the road but for now will haul the dump trailer behind it. Im seriously thinking of buying one of these but really dont know much about them. Any input on what to check for on truck and engine would be greatly appreciated. Dont know a whole lot on diesels so not sure what to look for.
