I'm buying a 5' x 12' utility trailer and fabricating / welding a 4' x 5' raised platform with reinforced expansion metal deck to mount RTT at the front of the trailer. I want to park a 4-wheeler below the deck w/RTT. I'm also converting it to SOA w/33" tires to gain some additional clearance for mild off-road excursions. How should I secure the RTT to the expansion metal deck? Any / all input is appreciated...
