So you said, "I just need some advice on how to get started". Well Randy, here are a few tips on getting started. First, you have to be committed, and the best way to do that is to get that trailer frame into your shop or garage. Some folks have custom made frames and wheels fabricated to their liking, but the easiest (and cheapest) way to go, is to buy a ready-made trailer, complete with painted steel frame, axle, springs, wheels, tires, fenders, tongue, hitch, safety chains, and brake lights with elect hook-ups to the hauler. That sounds like a pretty hefty order, but can be had at Harbor Freight for about 150 bucks, if you catch one on sale. It can be delivered to your place in just a matter of days, and when it arrives, you are on the way to building your own, one-of-a-kind teardrop trailer. I have used HF frames with 12 inch wheels, on both of my teardrops and have had no problems what so ever.
All you have to do now, is decide how long and wide it will be, the materials you plan to use and what comforts you desire to help you enjoy your camping experience. Some have been built for as little as 500 bucks, which requires a bit of scrounging, but depends on what materials and over-all looks you decide upon. Remember, as you said, you want a simple teardrop that is plain, but comfortable. Good for you, that narrows it down quite a bit. On this board, you can find some genaric plans that will give you some pointers regarding some standard methods and ideas that you will find useful. Remember, most of us have been right where you are right now and probably asked questions, just like you probably will. We are here to help, so just ask. Oh yes, take plenty of pics and post em, you can't go back and take em later. Try to make it to a local Gathering, or better yet, find a forum member living near you.
