Mike, this will be my 21st year driving and satellite radio is the best thing I've EVER put in a truck.
Think about it. Who DOESN'T have cable or satellite TV at home nowadays, paying at least $50-60 plus a month for it? And, when do they get to see it? AFTER they get home.
For pennies a day, you've got entertainment all day long AT WORK! I can all but guarantee you whichever one you go with, you're going to be kicking yourself for not doing it sooner.
A regular radio in a truck is ridiculous. If you do find a good station, you've got it for how long depending on what side of a town you're on? Thirty minutes? An hour? Then you're hunting again. Baloney. I push a button, I know what's going to be there. I see that the majority of trucks still don't have sat radio antennas on them and it boggles my mind.
I've had XM for several years. I will say that I've been around a couple of Sirius units momentarily here and there. Don't know if it was just timing, but I wonder if their classic rock might be better. XM has three classic rock stations, and two of them seem to have undergone a tremendous "softening." I do like their old time radio station (#164). Ride around late at night listening to old pre-TV radio versions of The Lone Ranger, Gunsmoke, Dragnet, The Shadow, etc. Cool stuff. They've got both, adult and cleaned up comedy stations. Pretty much every darned kind of music you could imagine. VERY good talk radio programs on #165.
My other half liked it so much when she'd go with me that she's got one in the mini van now. Don't know about Sirius and I can't remember by how much, but with XM a second unit on the same account is a lot cheaper per month. I've also got an antenna and cradle in my RV and dually. Whenever I take either anywhere, I just pop the receiver out of the truck and pop it into whatever vechicle I'm going to be driving.
Oh yeah, don't buy into the baloney that you have to have a "special" (read "money") antenna for a truck. I've had a regular car antenna cable tied to my mirror bracket (cause there's almost nothing on the outside of a truck for the magnet to stick to) for years. On my RV, I used my bandsaw to cut out a piece of 1/8" steel the same size as the antenna's bottom surface, then used A-B epoxy to glue it to the roof to give the magnet something to stick to. That way I can still take it off when I sell it.
