A: We take it that you are not referring to products that customize the look of a vehicle. You are referring to performance add-ons. If so, you should read the Magnuson-Moss Warranty Act, which is very clear about this, although it might take a read or two to fully understand the act. Look it up on Wikipedia (en.wikipedia.org).

The fact is the manufacturer cannot cancel your warranty merely because certain aftermarket products are installed on the vehicle. That's the spirit of the law. The warranty coverage can be denied only if an aftermarket part caused the malfunction or damage for which warranty coverage is sought. Disputes in this area usually boil down to arguments over facts and technical opinions, rather than over interpretations of the law.

The main point of interest here is that the act says that warranty coverage may not be conditioned upon the use of only the vehicle manufacturer's parts unless the parts are provided free of charge. And again, using an aftermarket product should not void your warranty unless it caused the problem.

A: The dealer should have explained the importance of proper hitch work during the sale. It is for your own safety and the safety of your loved ones. If the travel trailer you purchased requires a weight-distributing hitch, sway control, electric brake control, and wiring, then $900 is reasonable. Any reputable RV dealer will not sell the trailer without the proper hitch work.

Tool Time
Q: What tools do you guys use the most when you're creating your how-to stories? I'd like to buy a set of tools to keep in my truck.

A: Do yourself a favor and purchase the factory manual for your particular vehicle first. We don’t mean the owner's manual; the factory manual goes into detail regarding virtually every part on a vehicle, and it can outline what tools are needed for removing and installing critical parts. Obviously you can't fit every tool required in a small toolbox, but you can buy the tools that are most common to most areas of your vehicle. A toolbox is a work in progress. You will find yourself constantly adding to your collection until you are satisfied that you have what you need to make a repair on the road. Keep in mind that it's also a good idea to have on hand a can of Fix-A-Tire sealant, an air pressure gauge, some spare nuts and bolts, wire cutters, a small pocketknife, and mechanic’s gloves.

While some professionals prefer Snap-on Tools, Craftsmen is an affordable brand and fine for most small projects. Expect to spend anywhere from $100 to $300 for a good starter kit, which will come with an assortment of sockets, screwdrivers, adjustable wrenches, and perhaps a mallet or hammer. Don’t forget the safety googles!
