Our Big Daddy 25 and 30 Ton Dual Tri-Axle Equipment Trailers are built to make most lowboys jealous. These are the largest tagalong trailers available and we have plenty of experience building them. We recommend our heavy duty, 3 x 7.5′ hidden hydraulic, ramps to move large equipment with ease. Large main frames with 4 I-Beam construction with dual 2 speed bolt on jacks is a monster of a tag trailer.
