What do you want in Car Hauler trailer plans?  These are NOT another copy-cat or run-of-the-mill trailer.  We do the full engineering to make Heavy Duty trailers that will perform when you need them.  This is an I-Beam design which is tough so you don’t ever have to worry.  The I-Beams give strength while allowing the deck to stay low.  Put your truck on it, put your tractor on it.  Snag that perfect garage find.

A ton of study went into this design before the pen even met the paper.  Then, this trailer is one of the results.  With a Fixed Deck, slide out ramps, removable fenders, and a ton of other options – this trailer is made to optimize.

Yes, there are a bunch of different needs to meet, so choose the options you want.  If a 20′ long, fixed deck is the Car Hauler / Equipment Transport format you need, these plans will definitely carry your car, or truck, or tractor, or side-by-sides, or equipment, or whatever you need.

Engineering Analysis not Guessing

Robust design with full engineering – and a lot of options – in plans you can build from.  That’s Mechanical Elements, where we do the engineering so you don’t have to guess.  It’s all here in these Car Hauler Trailer Plans.

It’s as much a Car Hauler as an Equipment Transport, so drive on, and drive away.  See all the images above, then read the plans specifications below for more detail about the features.  We also have an article that talks about why’s of this trailer design.  Good luck with your project.

Fixed Deck Car Hauler Trailer Plans

10,400 lbs Total Capacity with tandem 5200 lb axles.  Strength is in the I-Beam construction, which is much stronger than C-Channel of similar size.  That makes this trailer perform better for the long term, and the long haul – especially if there are twisty or bumpy roads in your future.  Read more in the accordions below.

While it’s nice to think of one super trailer, the truth is, there are a bunch of various needs.  That’s why we give options.  Whether you’re hauling Cars, or some kind of Equipment, there are always options that make your job easier.

Make the trailer just the way you want it, and use the included options as a start point to build it.  These plans start with a firm base, then guide the build with options, and options of options.

We think customizing for the perfect trailer is the way to go.  Get the plans, then build the trailer you need.  Use the options within, or add your own.
