Okay, So, it's not really a flat bed but it was inexpensive and it has everything I need for the purposes noted in the previous post. It's a 4x6 with 12 inch wheels. The first thing that was apparent was the trailer is designed for landscaping so the suspension was very stiff, easily remedied.
(Before I go any further I have to admit I've pulled the kayak on the trailer with the stiff suspension (Thanks to Clif). But for the sake of the blog we'll pretend that hasn't happened yet.)
The first thing I did was remove the middle springs and flip the lower springs. This had a significant and positive affect on ride. I also reduced the tire pressure from 90 psi to 15 psi. I'm not concerned about over stressing the springs or the tires. The trailer and tires are rated for 2000 lbs. I won't get close 200 hauling the kayak and all that goes with it. The next thing I did was build a rack out of 2x4's, painted it black, then added soft plastic threshold beading to the tops to protect the kayak hull. Because the trailer is for landscape work I had to remove the tilt pin and add a bolt to eliminate all the rattling during roading. Here's the final result.
Part three coming up. And this time I won't make you wait 4 weeks for an update. I promise!
