PROLine Products LLC manufactures custom all aluminum enclosed trailers in Milton, New Hampshire. PROLine enclosed snowmobile, motorcycle, atv, contractor, car hauler and general cargo trailers have all aluminum frames that last and look good year after year.

PROLine aluminum trailers have screwless exterior sidewalls. This makes for a superior looking enclosed trailer and is great for putting graphics and advertising on the trailer sides.        

The all aluminum trailer construction maintains its original appearance and resale value, no rust and lighter weight than steel. Our aluminum trailers weigh much less than steel trailers, this means easier towing, more cargo capacity and better fuel economy.

PROLine leads the aluminum trailer industry with features and options like: translucent roofs, FRP  (fiberglass panel)  interiors,  hard roofs,
solar  powered  security  systems,  roof racks,
7' interior height and a side ramp door option.

We use cutting edge LED (light emitting diode) lights on our enclosed trailers for safety, reliability and less draw on your tow vehicles electrical system. We use Dexter Torsion Axles with E-Z lube hubs; the most reliable torsion axles available.

Prices are on our website, shop around, if you find all aluminum trailers that cost less, you're getting much less trailer. Our factory direct sales means you get more trailer for less money.
