Looking at a 2005 Chevrolet Silverado 3500 Dually 2 WD 6.6 Liter Duramax Diesel with Allison Automatic Transmission Work Interior includes manual window and locks, Vinyl floor and seating with front bench AM/FM Radio, Air Conditioning, Cruise With 9.6 ft DUMP BED and 2 ft cargo/tool holder behind cab (in front of dump) Dump has nice sides (heavy guage - see through and nylon roll top to keep load from blowing out) and truck is in really good shape with about 80K miles - (one owner - did brick and stone work) Questions is this a good truck? Feedback please. MPG loaded - Hwy unloaded? What will it haul (weight)?. I will be hauling just mulch or compost so I doubt I will max it out but curious? I would think it would pull 15,000 lbs easy? what something like this worth? No pics available just looking for your feedback on this model truck.
