I have been a longtime customer of SIDUMP'R dating back to 2003 and have always been impressed with the concept, speed and strength of the trailer. I like the improvements that have been made to the trailer, the hands on service they provide as well as their exceptional customer service. SIDUMP'R has one of the best trailers in the side dump market.

The SIDUMP'R trailers have been great additions to my fleet of equipment. I have used several different brands in the past and the SIDUMP'R line has fit my needs the best. We haul sand, gravel, dirt, trees, demo and scrap, rip rap, and busted concrete, and for these applications the SIDUMP'R trailer has proven itself to be the best. With the recent modifications to the frame and tub design, I am convinced that these trailers will last longer than any other in the industry.

We have found our operators assigned to Sidump'r Trailers don't want to miss work because they are then rotated back to our remaining end dumps. Our attendance rates have improved dramatically!
