Wharton,
Thanks for the TV advice. We are full-time, but bound to my work location. I manage large projects, so the life cycle is pretty long, and therefor don't move around too often. We've been in Florida for a little over two years. At that rate, it probably makes more economic sense to hire the rig/driver than it does to own my own. My truck is paid for, so it's a big bullet to bite to upgrade. I'd certainly like the flexibility and peace of mind of that, but cringe at the thought of making payments again.
If I could find the right deal on an MDT, I'd be interested. The problem with that would be the impracticality of using it as a daily driver. Then, a move would take us two or three trips to execute.
