That would be a nice add, although with the equipment available I think GMRS gets looked at more like a consumer grade hobby, rather than a technical grade hobby. However, I like the concept simply because I have done MRE's in commercial work. Both Public safety and Utilities. In utilities and LE, we sold and serviced PAC-RT's that were connected to low band mobiles, and those were VHF Hi, the PAC was .6 (6/10ths of a watt) on the mobile side and 2 watts on the handheld (HT600 Motorola). We also did it 450 handhelds to VHF mobiles for an ambulance district. For those of us who are adept...sure, I'd setup a VHF cross in my vehicle.
