Go with 2x4's x 8'ers, pressure treated, and space them out with a one inch space for drainage of snow and rain ...... about 30-days after installation, so the p.t. dries out good ...... hit it with a coat of exterior gray latex primer and two coats of high gloss, hard surface, exterior latex on the top and down in between the 2x4's as much as possible .....

..... 2x4's are relatively low priced, and very sturdy, and easy to add any later improvements, by fastening into the 2x4 construction lumber.


......you get to choose the color ...... maybe Arctic Cat super bright fluorescent GREEN and turn the trailer into a TEAM ARCTIC trailer and give it some attitude.

Walmart has perfectly decent exterior mixed-colors paint that is way less pricey than Lowe's.

And, having a trailer that's got some weight keeps it from bouncing all across the road, when it rolls across a bump or something.
