For us the issue of coach vs TC was safety. We often use truckstops/WalMart/etc for an overnight when we are travelling and throwing the miles down. A coach means you do not have to go outside to get in the tow vehicle if you experience an issue at 0-dark 30, you just slide into the captain's seat, turn the key, and drive away from the potential problem. have only had to do that once since 1989, but was sure glad we had that ability. Can't do that in a TC, TT, or 5er. So it really depends how you plan to use your rig. Having a larger rig and a smaller tow vehicle certainly has its advantages over a large truck and a large 5er - still tough to find a parking space be it at a grocery store or a tourist attraction. My 2 cents! ST
