I think that your first suggestion Dad Man, is my best option. I guess I will just have to run an extra cable to plug in when I need to transfer the bigger stuff.
I would never call a Holiday Inn Express guest lame, we still have the CB, handiest thing for local information we can get. The newer trucks are super fancy with our Qualcomm satellite communications.
Unfortunately coolspot, the current modem is proprietary, so I am not sure if it can be replaced. The handiest thing about it is that it is hard-wired to the trucks electrical system, bypassing the outlets. Although I may call them this week with some questions and mention your recommended replacements.
