When to use suspension dumps

It also puts a strain on the driveshaft if the truck putting you at risk of breaking a U-joint.

 

Had a trainer tell me you save you drive tires by dumping too.

 

Sorry to hijack this thread but would a sliding 5th be necessary for flatbed operations? Never swapping trailers.

Thanks

 

Especially with fresh grease on the fifth wheel.

 

I would think flatbeds have more erratic loads.

Running refer, I have not needed to slide my fifth wheel in two years now while balancing loads.

How do you dump the suspension on the tandems? I didn't know that was possible.

 

Really?!

Every air ride trailer I have ever pulled had a valve to dump the air. Usually back by where you pull the pins to slide the tandems. I dump the air on the trailer everytime I load or unload to keep from over extending the bags. That and its nice not bouncing around in the truck everytime the forklift goes in and out of the trailer.

I dump the drives when I unhook the trailer and in un-plowed lots during the winter to aid in traction. Honestly I dont know how or if it works but old timers all ways told me it helps and I have never been stuck so I continue to do it.
