50 Tips And Comments
I have been a devoted reader of 4-Wheel & Off-Road for many years, and I cringed when I saw yet another tips and tricks article ("50 Tips and Tricks," June '98). Wow, was I surprised! The article was informative and innovative and offered many nonduplicated ideas. You even borrowed some street-rodder tricks and tips. Great job!

Great ideas in the "50 Tips and Tricks" article, but you might want to check the suitability of using PVC pipe for compressed air in a shop.

While serving on the safety committee for a large university several years ago, I remember seeing a warning not to use PVC pipe because it can suffer catastrophic failure. I also believe a similar warning was printed in the US Plastics catalog some years back.

There are some cons to using PVC, namely it may shatter if something heavy falls against it. However, if you check the burst pressure printed on the tubing, it is possible to get PVC rated at 300 psi or higher, so failure due to internal pressure isn't a concern. The pros are that it's inexpensive compared to steel, and it doesn't rust like steel lines do.

'99 GMC Sierra
In reference to "'99 GMC Sierra" (May '98): Man, what a truck! Now, can someone just tell GMC and Chevy to build a bare-bones, inexpensive, off-road model for those of us who can't afford and don't need the gee-whiz factor? Oh, and one more thing: For the Yukon/ Tahoe debut, think removable hardtop.

A removable hardtop would be cool and retro, wouldn't it? As far as bare-bones models, GM has produced a work-truck version in the past that has rubber floor mats, hand-crank windows, and so on-we assume they'll continue with this model.

Driver's Ed
I just read 4xForward in the June '98 issue. I couldn't agree more with the entire article! Coming from a law enforcement point of view, I think that everyone should be required to take driving instruction that goes beyond the basic driver's ed class in high school. I get tired of pulling people over for the simple little things (changing lanes in the middle of an intersection, not yielding when entering a roadway from a private drive, and so on), and getting the same question: "What did I do wrong, officer?" I saw a guy yesterday eating spaghetti while he was driving!

I mentioned two on-road driving schools, but there are also a few off-road schools that teach vehicle control and terrain reading, which is handy both on- and off-road. Here are a few of them: The Adventure Company (Dept. 4WOR, 8855 Appian Way, Los Angeles, CA 90046, 323/848-8685), Four-Wheeling America (Dept. 4WOR, 2134 S. Humbolt St., Denver, CO 80210-4619, 303/778-9144), Moses Ludel's 4-Wheel Driving School (Dept. 4WOR, P.O. Box 584, Yerington, NV 89447, 702/463-5965, e-mail, Land Rover Driving Academy (Dept. 4WOR, Land Rover North America, 4390 Parliament Pl., Lanham, MD 20706, 800/FINE-4WD [346-3493]), Rod Hall Off-Road Driving School (Dept. 4WOR, 1360 Kleppe Ln., Sparks, NV 89431, 702/331-5032), Rovers North Off-Road (Dept. 4WOR, Box 61, Rte. 128, Westford, VT 05494-9601, 802/879-3534), and West Coast British (190 Airway Blvd., Livermore, CA 94550, 510/606-8301).
