Safety First.
It's a good idea to spend some time poking around on the different forums on this site (I lurked for about 2 yrs. before starting my build thread). There is a wealth of knowledge that can help better prepare you for the journey that you are about to start. Make sure that you know what you are getting into, plan ahead, realize what your whole budget will be before starting (no matter how simple you plan your build, there will be an accumulation of costs and unforeseen expenses...the experience of the others that have gone before you will help you immensely).
Decide if it is more important to finish and get camping, even if you may not be totally satisfied with the end result, or, if you want to build for the long haul and hope that you can realize your vision the first time (rare, but we can at least dream).
Recognize your skills and limitations. If you are unable to use power tools, you will need to allow more time, and/or farm out those tasks. Budget this in your schedule or planned costs. Don't underestimate. (Emphasis on the period.)
I am not offering these sentiments as a discouragement, but rather as a reality check to make sure that you get the most out of your build and to help you achieve your goals realistically. I struggle with my own build on a regular basis, wondering if I can really do it in the time that I have set for my goal, if I can achieve the quality level that I have envisioned (no matter what that level is or is not). Only you can decide if this is right for you. We are here to help.
Sorry if this sounds sappy, but I have struggled with all of these issues and have gleaned a huge amount of help from those that have gone before me. This is a major undertaking, no matter how simple you intend it. Plan, plan, plan.
You may want to start by looking at the "Trailer and Chassis Secrets" section, and then read the big "Thrifty" thread in the Foamie section (there's a lot of character in there...sort of a rite of passage, but it will help you understand what a basic Foamie is and is a leaping off point to all of the other Foamie information).
Good luck.
BTW, I tend to be wordy.
