Just got this in about 2 weeks ago to add to our other 2,500g tanker. Going through it now adding more lighting, radio's, MDT, etc. The only thing that went sour, was being able to get an extended front bumper for a mechanical Q. Found out that was an after thought, and too expensive to add on. Otherwise, the 3 rear dump chutes should work pretty nicely for the drivers.
Anybody have any issues using a KW as a tanker??? Don't expect any, but who knows. :)
