Cargo trailer conversion...bad idea?

Hi all,
I am looking for some (semi) professional advice as to whether or not my current hair-brained idea is a good one. I am a seasonal worker (forest service, stream restoration, river guide, etc) and am at the point where I would like too have a reliable, cozy, but still mobile roof over my head. Building out a cargo trailer seems like a great option but I want to be sure it is safe for me to tow before I dive in.

I have a 2003 tacoma. It has a hitch welded to the frame and is wired for brakes and lights. I read through the towing bible (thanks maverick491!) and it seems like the biggest concern is braking capacity. Would trailer brakes solve that issue? Are there other things I should be keeping in mind?

I have been looking at 6x10 or 6x12 cargo trailers and think I could keep the trailer weight to 3000 lbs with a build-out. Is that too much for my truck's 3500 towing capacity?

For more context: I only expect to move this trailer a couple times a year (300-600 miles or so) so I am more concerned about safety than wear on the truck (I think).

Any advice would be much appreciated! Thanks!

 

Personally, after having driven my 99 through some mountain passes I would not trust one of these truck to tow anything at all. The braking power just isn’t there, and the whole system is 20+ years old.
