ADVENTURE TRAILERS PRODUCT REVIEW

Without the suspension system that Adventure Trailers did on our M416 trailer we would have certainly fought the road and the original suspension the whole way. We were continuously amazed along the way with how well the trailer pulled and absorbed everything we threw at it for terrain from old rough back roads, sharp unexpected diversions, crossing the highway medians to having to pull off of the road as we drove to let traffic by. This suspension system work phenomenally well and we are excited to get this thing back to the team at Adventure Trailers for more of their equipment upgrades starting with the “lock and roll hitch”. We hope to be equipped with our own Chaser model trailers for the next road trip since we plan to be in a outdoor setting and will be using them to live out of along the trip.

M416 MILITARY TRAILER SUSPENSION REMOVED AND REPLACED WITH AN ADVENTURE TRAILERS PATENTED TRAILING ARM, AIRBAG, SHOCK ABSORBER (TAAS) SYSTEM...

Scott Lacey, AT's Shop Manager removes the original leaf springs and solid beam axle and replaces them with the Adventure Trailers TASS system. The complete job could easily be done in a weekend by one person, although an extra pair of hands would help.

The first step was to remove the solid beam axle, and leaf springs. The trailer was then turned upside down and the spring mounts were cut off. With the trailer upside down Scott was able to get a good look at the condition of the chassis which turned out to be in good condition. Scott's next step was to take some measurements along the chassis to make sure it was running parallel and square and then started doing some layout.

The new suspension would consist of a cross member made from 2x3 rectangular steel tube, plates for the trailing arm to pivot from, pivot rods and bushings, trailing arms, upper brackets for the airbag location, airbags, shock absorber brackets, and shock absorbers. The airbags would have 1/4" air fittings and 1/4" air line for inflation.

Once the correct location of the trailing arms had been determined the cross member was welded into place to the outside and underside of the chassis (when the kit form of the suspension becomes available it will be a completely bolt on unit). The trailing arms were assembled and located into the cross member so the exact location for the upper air bag bracket could be marked. The brackets were welded into place. We were lucky with the placement of the original cross members as one was right where the airbag bracket was to be located and the other where the upper shock absorber bracket was to be mounted. Some things are just good fortune and dumb luck!

After fitting the bearings and hubs we refitted the original tires and rims and rolled the trailer back upright. We aired up the air bags to get 6 inches of travel and Scott hooked the trailer up behind his Cruiser for a test run.

When Scott finally got back to the shop he had a huge grin on his face. The trailer modified with the AT suspension gave a smooth ride on the test course and didn't exhibit any of the bouncing or the rough riding the original trailer has shown on washboard and varying terrain.
