I finally got to build my new trailer!!!!!!!! Here's the breakdown of the cost:

axles (tandem), axle mounting hardware, hubs, fenders, springs, coupler, jack, welding supplies - $395.00 from Agri-supply in Florence SC

steel ( {6}2x2x1/4 angle, {10}2x2x1/8 angle, 2 4x8 sheets expanded steel) - $390.00 from Hartsville Steel

wheels and tires - $20.00 (wheels were free, 4 slightly used LT245/75R16 uniroyal tires from someone who owed me a favor)

wood - 11 2x6x16 treated, 4' saftey chain, 2 hooks - $190.00 from Lowe's

paint - 24 cans flat black spray paint - $25.00 from Wal-Mart

final total cost - $1020.00

A friend helped me, took about 30 total labor hours. Final dimensions are 68" inside useable space, 16' total length, 4' loading ramp, 2'x2'x68" lockable expanded steel box on the front raised so you can pull ztr flush with the front. Have 3 lockable trimmer racks mounted to the back (trailer bed) side of the lock box. It feels wonderful to not have two people chasing each other around to each yard anymore using twice the gas!!!!!! Anyway, a new one in this area built the way mine is retails for about $2000. If I could pry the digital camera away from my wife, I'll post some pics.:drinkup:

In the steel all I see listed is 2" angle. Tell me you DIDN'T just use 2" angle for the main trailer frame? If you did you sure as heck hurt your payload weight badly. No way you'll be sturdy enough for a GVWR of 7,000# that you would have on just a standard 16' dual 3500# axle trailer. You needed to use 4" mininium and even better yet 5" channel for the main frame. 2" angle is fine for the sides and braces but not the frame.

You also could drive 2 hours north of Florence to Denton, NC and get a high quality 7.5' wide x 16' long dual axle with 5" frame for $1500.00

The weak point is the tounge weight .

Agreed. But also not only that but if he used just 2" all the way around just try putting the 5,000 lbs on there it "should" hold and watch it give or even worse buckle. For a little single axle 5x10 trailer 2" would have been fine, but not for a 16" dual axle.....2" just isn't strong enough in the long haul big picture. At least not for carrying the weight it should, esp when you consider that you could buy a professionaly engineered and built one for just $500 more.

But, that's just my opinion....which means nothing... :)

True we built a 5 by 10 in the late 90's out of 2 we got a lot of sags looking down the trailer it was for light duty.

the 2" is reinforced at stress points, tounge, suspension mounts are all bolted with grade 8 bolts as well as welded. also, frame is reinforced with additional horizontal and perpendicular support crossmembers which tie all stress points together. entire frame is actually over-engineered. i had my uncle who is a structural engineer verify the design for strength prior to build because it would suck to have it pass me going down the road.

also, is designed for 5k not 7k.

so $1020 for the materials and 30 hours labor at 50 an hour brings your real cost up to $2500.

IMO there are just some thing that are best left to the proffessionals to build...

Then you have 2,500# axles?? WHY? Esp on a 16 footer

2x2 for the frame is not enough. you'll see that start to bend after a year especially if u have a ztr going on that trailer. Walkbehinds would be fine but the frame wont handle the ztr. I had a trailer made and the guy used 2x2 and it bent behind the second axle towards the back. Not an actual bend but it shows when you look at the trailer. Just my .02 cents on it.

The 2x2 1/4 angle even if it dosn't bend it's going to twist and flex like a mother. your mowers are going to think they are on that bridge that was named "galloping girdie" going down the road!

I have priced building a trailer a couple times, first was when I was in highschool in shop class and then another time a few years back. Neither time could I even buy the raw materials for what one already built, painted, wired, and ready to roll cost.

Building things is fun.

Any pictures of the build, it might help some other people... I hope it works for you and saved you money

Here is our latest project, To be able to fit 2 36 and 1 48 in a pickup truck and use it to plow snow, we are not yet finished.
