Building a 6x10x4.5' squaredrop of my own design for Mrs. Boss and myself.
I ordered the Northern Tool 5x8 steel trailer thru Amazon, shipping was $140 vs $540 from NT direct, that would have been the deal breaker.
I scoured CL and OfferUP for weeks looking for one, but anything reasonably priced had scaly rusted frames and rotten tires, I don't want a trailer project.
The local dealers rarely had anything used, and they wanted a mint for them, and steel prices are thru the roof 2-3 times higher than 2 years ago, so fabbing one up was out of the question.
So lets put it together.
Oh wait, I may be missing a part or two.
Best I can tell I have all the frame parts, waiting to hear back from NT and the freight company as to where the axle, wheels, springs, fenders, hitch coupler, lights, wiring and hardware are.
Freight ticket lists 2/3, sounds like a big box for the rest of it.
The freight company has had it at their facility an hour north of me for 18 days, they were 9 cans behind schedule.
I'm not upset about that, I've been dealing with this stuff at work for nearly 2 years now trying to remodel houses. One week I can't get plywood, the next week I hit 7 stores to find the last electrical remodel box in all of Seattle. Seriously, it can be like finding TP was early 2020
Anyway...

*Custom built windows (I have another idea) Tap plastics is only a mile down the street.
Star gazzer
And a bunch of other bits
Planning a cedar strip ceiling and back wall (scored at work), thinking of doing a padded wall covering, maybe headliner, a heavy fleece or felt.
Not doing shore power, at least at this point. I'll put in the receptacle for it and use it to charge the battery.
* Window choices are slim right now and polycarbonate is 1/2 the price. A little extra work for something I'll be happier with.
Scavenged plenty of 2x4's from work to resaw into 2x2's
I'll probably be able to save some other stuff from the trash along the way.
My work buddy, the company cabinet builder, scored me some nice high quality cabinet ply scraps that should work nicely for the galley and cabin storage. Sounds like there might be some hardwood scraps coming to use for trim work.
I'll have to buy all the wall/flr/roof sheeting, it would be a lucky score to get the grade/type in the thickness I want.
I've been remodeling houses for 30 years, but I've watched all of the youtube videos, except for that one guy.
Doesn't hurt to see how others do it, as well as learn from their mistakes.
Joke of the day: I'm shooting for a $3500 build.
That's what was negotiated with Mrs. Boss
