New Build - 6*12 Offroad Toy Hauler

[SouthSide45]

Newby here (first post)in the gathering info stage,
Your build is amazing and covers pretty much everything. Just spent a week going through it.
For me, a person with limited to no experience in carpentry,plumbing,electrical,etc., your build is unrealistic. Not sure exactly what I want other than to be able to tow it (smaller tv) when needed and thus why I'm considering a ct conversion. A trailer builder down the street from me want north of $12,000 for a trailer with only a few things including insulation,wiring, AC, etc. Colorado Trailers want $18,000 + for half of what you included in your build.
My plan is to sell my small boat for around $10,000 and that should provide some funds and a place to put future build.
Are you aware of a good place to start for a simple 6x12? I'm more of a imper perfectionist and functionality over form. Just want to build a bug out platform. Probably need a lot of bungee cords to keep all the loose things secure.

Thanks for all of the information, wisdom and knowledge that you have provided in your posts,
