I agree with the comments above....
I'd get a decent HT but keep it cheap, then buy a mobile for the truck. you could stay under $400 and have two radios and be a lot happier. Like Wes said, the mobile in the truck is way better and easier to use than the HT. The HT is nice to have when you are walking around outside of the rig or in your house or something.
We usually leave the Mobile in the kitchen. When I'm in the garage me and Allison can chat without a phone call if she needs something since my truck has a radio in it too.
I got a VX-7R and I am just now (after 3 years of ownership) starting to use some of the features it has beyond 2m. I'd have been fine with a cheaper one personally, but now that we have it it is kinda nice.
