I just replaced my old "tow car" (1995 Chevy Suburban) with something very similar, a 1999 Chevy Suburban. Same color, even. The "Burb II" is 4wd, where the old one was 2wd. Both had/have 350 v8s with throttle body fuel injection. The "new" one has leather interior. I really don't like that. So it got a set of "suede"-like seat covers. Much more comfortable now. It might look a little strange, but I like it better.
And of course ya gotta have a good stereo to listen to Pink Floyd, Led Zeppelin and Ten Years After on, so I popped a Kenwood unit into it. Yes, I'm a "child of the 60s" and enjoy rockin out to progressive rock from that era. This stereo has a USB port on it so I can copy mp3 files to thumb drives and change 'em around whenever I feel like it. Surprisingly enough, it sounds great with the stock speakers and no subwoofer or additional amp. Ohh...it also has an iPod/Android interface so I can use my Droid as a music player if I want, too.
Then I installed a "rear view camera" and screen because I've covered the rear glass with reflective/foam insulation since it gets REAL hot on the salt flats and the Burb is my "Hotel Suburbia" for at least 2 weeks, sometimes 3, every year. When it's 105F (40.5C)+ outside, the last thing I need is sunshine heating up the inside of the thing. Anyway, that made the huge blind spot ever "huger" so I decided that instead of running over my neighbors' kids and fighting with connecting the trailer, I'd go kicking and screaming into the 21st century and for a coupla hundred bux I got a camera with a 7" screen that really helps.
I also hang a drape behind the front seat so that the air conditioning only has to cool a small area. There's a huge volume of air in the rear and insulated or not, it takes a long time to cool it.
Now...if I can just get the race car ready in time, I'll have something to tow it with...but progress is being made. Last nite I decided to quit fighting with the "racing seat" I'd picked up at a swap meet and buy "real racing seats." I bit the bullet and ordered a pair of 'em that includes adjustable mounting frames and adapters. I only have one set of 5-point harnesses, but that'll have to do for the moment...at least until I find a victim passenger who wants to ride along when I get to the point of doing a bit of road racing with it. Uh...that's the 85 Monte Carlo, not the Burb.
