Freightliner & Truck Camper

Sharp looking ride but it's going to require a serious lift platform in the bed to get the cabover on the TC to clear the truck cab. The Kodiak needed added lift for cab clearance too I think. You'd be better off to stick with a truck from one of the main 3 truck manufacturers F, C, or D for compatibility. Buying that truck for hauling a truck camper would equate to more dollars than cents so to say. Unless that's your financial status and you don't care about cost, then you should be able to pay for any modifications needed to make the setup work. The new trucks have been looking pretty good to me. The new larger gas engine that replaced the v10 seems to be very good. If you are going to tow and need that diesel, the 6.7 seems to be a very good engine too. If you need the load capacity, the 450 4500 and 550 5500 sized trucks should accommodate you.
You'll figure out what you need before long and all will be well.
