When Should I Build? – When Should I Buy?

Do you want a new Utility Trailer?  Or, an OHV Hauler?  We have plans for those, but the big question is:  When should you build your new trailer?  versus  When should you just go out and buy one?

These are great questions, and we have some opinions (not what you might first think).  While this discussion is in the context of trailers, the same is true for Gantry Cranes, Shop Presses, and many other DIY things we can build or buy.  We will look at several aspects of building a trailer one at a time.  We will end with a conclusion for each.

Material Cost To Build A Trailer

Cost is one of the big reasons people give for wanting to build a trailer.  Go look in a trailer yard and you might get sticker shock.  Search the ads and you might find only overpriced junk.  Often we feel it will cost less to build than to buy.  Is that really true?

Almost all of the new trailers you see on a lot are made in a factory.  Those factories buy their materials (steel, aluminum, etc.) at rock bottom prices because they purchase in very large quantities.  They also use the materials more efficiently because they build many trailers so they do not have as much scrap per unit.  The same quantity pricing is true for all the components like Axles, Wheels, Tires, Hitches, bolts, wiring and more.

Conclusion:  For raw materials and for purchasing components, unless you have some amazing hook-up with a supplier, a factory buys everything cheaper.  Cost advantage for “Buy”.

What About Labor And Other Costs?

Factories have to pay people to build trailers.  They also pay to ship finished trailers to the dealer lots, and allow some profit margin for their retailers.  They must make a profit too.

Do-it-Yourself builders, do pay a higher price for materials (and components), and it does take us a lot longer to build a trailer than a factory.  But, we do not pay shipping on the finished trailer, and we do not pay retail profits.  (Well, not on the finished trailer.)  Our profit is effectively the pride of ownership, and a finished product that we made.

Labor, on the other hand, is something we pay in opportunity cost.  Time we spend to build a trailer is not paid, but it is time that takes away from something else.  What is your time worth?  That is the cost of your labor.  Yet, if you are like me, the enjoyment of building and the satisfaction of producing something really great, is also part of the pay.

Conclusion:  There is a good case for DIY with the lower financial cost of labor, but labor cost alone is not a convincing reason.  Satisfaction in your work, and pride of ownership, well, that is another story.  Cost advantage for “Build”.

The Value Proposition

We will go into more of the details below, but one big cost factor is getting what you want.  If you buy a trailer, you might have to take what they have on the lot.  If you want something custom, or if you want something not on the lot, then it might take some time.  And, the extra options can be very expensive.

If you build a trailer, you can include more of the options you want, and adjust the size or Customize the trailer in other ways.  The cost for these improvements is just the time and materials necessary.  The one hiccup is that it takes a lot of time to build as comparing to buy.

Conclusion:  If you want some special, or custom options, the DIY approach is attractive for cost.  Cost advantage for “Build”.
On the other hand, it takes a lot more time to build than buy.  Advantage for “Buy” — unless you have to wait for months and months for a custom option.

So, When Should I Buy?

If you want or need a trailer that is just like the ones on the lot, then you should probably buy one.  In the end, factoring in the cost of materials, components, time for fabricating, building, painting, and extra tools you buy, it is likely to cost more to build than to buy.

Is it heresy to say that? Keep in mind that I am talking about a factory standard trailer.  If that fits your need, and it is all that you want, then it is probably better to buy one.  If cost is a concern, search the ads on Craigslist and other places.  It is not uncommon to get a good deal on a standard type trailer.

Two other reasons to think twice before you build a trailer:  Tools & Space.  If you do not have the right tools (or have access to needed tools), building will be much more difficult.  Also, you will need plenty of space to setup and build a trailer.

Finally, if you need a trailer right now, it is hard to build one really quick.  Better to just buy (or rent) what you need, then worry about building something later.  That is – if you are so inclined.

Why Build A Trailer?

Building a trailer is a wonderful experience.  If you are thinking about this kind of project, there are lots of reasons for building, and many may apply.  Here are the reasons I see to build a trailer:

Functional Reasons:

1. If you want something different from the standard factory trailer, definitely build it.  When building, you can customize the width, the length, the axle placement, tongue length, etc..
2. If you want custom options – like certain sides, a specific tailgate, a given spare tire placement (or none), a certain decking type, or any number of other options.  Building gives you the ability to customize the trailer any way you want.  You can make it perfectly fit your ATV, your tractor, your mowers, or whatever else you intend to carry.
3. If you have a specific need, you can build a trailer for your Jeep (off-road camp combo) or your car (low, lean and efficient), or whatever you intend to pull it with.  Truly custom projects may have other economic considerations.
4. When you are building something truly unique, like your new Tiny House, build the trailer that gives it the best foundation.  Or, when adding a folding tongue or other major option.
5. If you want a trailer that is robust from the start, build it.  Factories build trailers as cheap as possible to meet specifications and not much more.  They take short-cuts like using angle iron for the frame, then support it with short sides.  (This works great for an even load, but fails if the sides get damage or if the trailer load is obnoxious).  You can certainly build one better.
6. When you build, you can address things like trailer bounce right from the beginning.  You can bias your efforts to the things you feel are functionally important.

Intrinsic Reasons:

1. Then, there is the pride of ownership.  Once you build a trailer that is really great, you will have payback every time you see it.
2. Finally, if you love building — if creating is part of your mental relaxation — then build a trailer, for sure.  It is a perfect project.  (Personally, I almost always like the shop better than the couch, so I get it.)
3. If you want a truly quality product.  Perhaps you are meticulous about how things look, or want a custom finish.  Quality is a great reason to build.
4. Education.  There is nothing like the education that comes from a great DIY project.  You will learn a ton, and if you are like me, your children can learn right along with you – especially teenagers.  (I have great memories of working with my sons in the shop.  –  I do not have daughters, or they would probably be learning too.)

Conclusion:  No question, if you want something different, if you want something really robust, if you want something you can be super proud of, and if you have a love of creating and building, DEFINITELY, Build It !!

Final Thoughts – Summary

The case for building over buying is one of ending up with something that truly fits your needs.  As noted above, it is not just a matter of cost, but also of enjoyment in the final product.  In our plans, we show lots of options, and we encourage customization.  Build a trailer that you are proud of, and it will be a source of joy for years to come.

I have always said, “Build it if you want something you can’t Buy.”  That means quality, toughness, customizations, opportunity, education, pride of ownership, etc..  That is why I build.

For your tiny house, the foundation is the key to almost all other parts of the project, so yes, build that to meet your needs.  We have some great plans to start with including a 20 ft, a 24 ft and a 30/32 ft option to choose from, and customize.

Another point that we sometimes dismiss — enjoying the process.  The love of the journey!  Learning and expanding in ways that provide enjoyment is pretty important.  It adds richness to our lives.  Do not discount that.

I might add that there is also a priceless education that comes from building something, especially if that is not what you do every day.  Learning more about yourself and about how to do things will benefit you much farther than just the accomplishment of what you build.  I say “priceless” because there is no better way to learn than to do-it-yourself!

Good Luck with All Your Projects!
