Every one of these is a place the number could be off. They are here because you should be able to check our working, not because we are hedging.
THE FIGURE PEOPLE REPEAT IS THE BOX, AND THE BOX IS ABOUT HALF OF IT.
This is the whole page. When a builder says they made theirs for a number, they are almost always naming the trailer and the shell, because those are the parts you can stand next to and photograph. The galley, the electrical and the interior are harder to point at and they cost nearly as much, so the repeated figure is true about half the build and silent about the other half. At our defaults the rolling box is $2,700 and the fit-out is $2,400, which is the finding in one line: the part that gets quoted and the part that gets discovered are almost the same size. None of the second half is hidden and none of it is exotic, it is just that it arrives as parts orders over months rather than as one purchase, so it never assembles itself into a figure the way the trailer and the plywood do. Adding it up before you start is the single most useful thing this page can do for you.
The fit-out is the line to get right first, because it is the one that gets deferred.
The galley, the battery and the lights, the insulation and the mattress: this is what turns a box into a camper, and at our defaults it is $2,400, a shade under what the rolling box costs. It gets deferred because none of it is load-bearing, so a build can look finished from the outside while the inside is a plywood shell with a mattress thrown in, and the temptation is to tow it like that and add the rest later. That is a fair plan as long as you priced it, and a trap if you did not, because the later parts are the ones that decide whether the trailer is usable in the cold, whether you can camp away from a hookup, and whether you actually cook on the road or just sleep. Split your own fit-out into what makes the trailer usable and what makes it nicer, spend on the first before the second, and put the whole figure on the ledger now so the build has an honest finish line rather than a moving one.
The tools are a real line, and half of builders write zero here honestly.
A teardrop asks for a few tools a general toolbox does not carry, chiefly for the curves and the clean sheet cuts that give the trailer its shape, and at our defaults that is $400. The line is genuinely split down the middle: a stocked workshop writes zero here and means it, and a first build from a bare garage can spend more on tools than on the galley. Both are honest, and the wrong move is leaving the line off, because a tool you bought for the trailer is part of what the trailer cost even if you will use it again. If you will use it again, that is a real argument for the spend, but it is an argument about your workshop and not about this trailer, so make it on purpose rather than folding it into the build and pretending the trailer was cheaper than it was.
No build-hours total and no resale figure, because those are the two we have not measured.
They are also the two you would most like us to print, so it is worth saying plainly why they are absent. A self-build is months of weekends, and that time is real, but this page will not put a number on the hours, because we have not measured them and a made-up figure would be read as a fact and then used to talk yourself into or out of the build. Count your own time if you want it on the ledger, and be honest about whether the build is a cost or a hobby you would have spent the winter on regardless. Resale is the same story with more folklore attached: a well-built teardrop can hold its value and a rough one can be worth the scrap in the frame, and the gap between those is workmanship rather than any average we could publish. Look up what finished builds like yours are actually selling for, use what buyers pay rather than what sellers ask, and treat the answer as being about your build rather than about teardrops in general.
This ledger is the build, and it stops when the trailer is done. What is above is materials, fittings, tools and the plate. It does not include the tow vehicle, which a finished teardrop is usually light enough not to need changing, nor the hours the build takes, nor what it costs to own and store and insure afterwards, and across a few years those last are not a footnote. If you are cross-shopping a build against buying a finished one, run this page to get your honest build total and hold a seller's price up against it: a bought trailer skips the winter of weekends and starts with someone else's workmanship, and whether that is worth the premium is a decision this number lets you make with both figures in front of you. Finance charges are absent here too: this is what the trailer costs, not what a loan on the materials costs.
