I'm selling my 85 GMC 1/2 ton pickup that I have been using for the lawn biz and my 94 Jeep Cherokee that is my personal car and replacing them with one newer vehicle which will be both my daily driver and my lawn vehicle. I only mow part-time (10 lawns) and teach high school full-time. I have 2 kids, so extended or crew cab is a necessity. I run everything out of the truck bed - no trailer because I have no where to park one and some of my lawns would be very difficult to get to with a trailer. Also, I do occasionally pick up mulch and landscaping jobs as well for extra $$$. I'm looking at a 98 Chevy 3500 4x4 crew cab, dually, 5.7L V8, 65K miles for $15,900. Is this going to be too much vehicle for daily driving? How bad will the gas mileage be? If it were a single rear wheel, I'd buy it in a heart-beat, but I'm not 100% with the dual rear wheels. What do you guys think? How would it be for regular driving? Any other suggestions?
