View attachment 336143Did an initial testing of our three point sub frame. Looks as though the truck frame can flex greatly without any flex making it to sub frame. The rear pivot mount is secured to clip angles that bolt through frame. Some pivoting is noted here at full deflection. This is critical to reduce the chance of binding original frame and allowing its full free movement. The main pivot allows for up to 10 degrees of flex either way. The clip angle mount appears to allow some movement as well. Note how the front is secured-bolts over springs that screw into existing frame drilled and tapped holes. We did not notice much compression of these springs at full flex.
At this point of full flex, the front wheel of truck was just starting to come off floor.
We did observe clearance at every fixed object on truck frame at full flex. Looks like we have a nice functioning sub frame at an economical cost.
Note the clips that extend beyond sub frame-these pick up mount spots on camper shell. More to come.
