Buy a 4x6 or 4 x 7 trailer from Tractor Supply Co. or Northern Tool. (629 bucks - but look for a coupon or sale) Carry-On Trailer is the brand. Northern Tool has the 4 x 6 without back gate for 529.https://www.tractorsupply.com/tsc/produ ... _vc=-10005
You can either keep the back gate on to use as a second support for the yaks or take it off. I had them sell it without the gate, and installed some wood slats to enclose the back. That takes some money off the trailer.
Then buy and install pickup truck bars (Vantech is mine) with kayak cradles. https://vantech.us/P3000-Bolt-On-for-St ... 0-BOLT.htm
I can fit two Hobies (an outback and a PA 12) on mine comfortably, and can you lay two other yaks in the bottom. The picture on the Vantech website shows four on one set of cross bars if you turn on their side). https://vantech.us/searchquick-submit.sc?keywords=kayak
You can also buy and install a plastic bin that locks for gear, which is what I did. I cut holes in the bottom of the bin, ran a chain through them and the lattice of the trailer bottom, and then connected the chain using a padlock inside the box which also has the benefit of keeping the box in place on the trailer.https://www.walmart.com/ip/CONTICO-Port ... 5/19514860
I have used the trailer for other applications, and I love it. The trailer bars are at a perfect height for loading and unloading while leaving room at the bottom to access the carry bins. I have had for about 3 years now, and I repack the bearings every season with grease and that's the only maintenance I do on it. Sometimes I rinse it off at the car wash when I am washing the yak, but it is pretty painless. I also like that it doubles for storing my yak in the garage and other things, and saves me a ton of time each trip loading and unloading.
Same price (or cheaper) than a Malone, more versatile, rated for 1750 pounds (unlike the Malone) and fun to put together and customize.
