What you need to do first is the most important step......evaluating your capabilities.....if when you evaluate your skill set, to only find a desire to do this; that is not enough; no where near enough.
The skill sets reqired to complete a full restoration are as follows:
1) Project management: Where will you work on the trailer? If outside in the backyard; not good enough. Ability to complete a work completion schedule and budget that is realistic and attainable; keep in mind the old axiom that your budget should be at least twice what you think it is, and take three times as long to complete.
2) Ability to know and calculate weights and weight distribution. This really applies to trailers; get it right, and your trailer tows like a dream; get it wrong, and your trailer will tow you.
Below are other talents and capabilities that you don't need to know, but knowing them will save you a lot of money.
1) Electrical, both
12V and 110V. Why is
12V wire stranded copper and 110V solid copper? What is a GFCI? How to test for conductivity and find ground faults.
2)Plumbing, PEX A, Wirsbo, Uponor, ring clamps, crimp rings, ABS types and usage.
3) Cabinetmaking: how to build a cabinet that will hold drawers and items but have no bottom, back, or even a top (the counter top is the top of the cabinet). Faceframe construction, Lamello, Domino construction. Materials that are very strong but as light as you can find.
4) Upholstery, making your curtains, beds (especially if curved at one end).
5) Metalworking, welding, media blasting. painting; I could go on and on.
All this takes time, materials, a good space to work in, and most importantly determination and knowledge that after most days of long hours, you may have little to show for it.
For every gut and full restoration seen to completion, twenty+ trailers are gutted and then sold with the line "gutted, ready for your dream interior; all the hard work done"
.
Look at yourself first; a long hard look.
