Hey guys, I'm in need of upgrading my towing abilities and suffer from sticker shock as far as buying new. I'm looking at '03 to maybe '07 3500's. Don't really need 4 wheel drive but I want the highest GCWR since I'm planning on a heavier fiftth wheel. I need some help regarding what year Dodge went to G56 transmission or how the 48rfe's hold up. If I go auto, I'll plan on a rebuild at some point. Also, do all the 3rd generation trucks have the same size brakes ? And what year seems to be the best as far as mileage and reliability goes. I've got a '95 2500 ext cab 4x4 that's been amazing (over 255,000 miles with no problems) but she just doesn't have the towing ability for what I need her to do. Looking at up to 16000lb fifth wheels. I appreciate any suggestions and info.
