I'm looking to start a construction business for myself and family and right now deciding on a work truck. I'd like a full size 4x4 crew cab w/ under 130k miles for around $6,000. Although I'm open to F-150s and Silverados the market seems to be steering me to the Dodge Ram 1500s as they seem to be a little less expensive. I'll be working out of the truck all day and it'll need it to stay running pretty much all day with the a/c blowing, not an easy thing to ask from a vehicle. With my $6k price range, cars.com, autotrader.com, etc. is showing Rams in about the 2000-2006 year range. So I'm writing in to ask you guys about Rams in this year range. Are there any I should look out for or any I should avoid? Are there any with durable features where I should consider upping my price range a little?
