Hey gasman, Do you know how much your lid end up weighing? And what size gas struts are you using?
Mine should have weighed in at about 105 lb, but actually weighs about 150 lb. The reason for my weigh change is that the fab company used 12 ga. metal instead of the 14 ga. that I had figured for them to use. Not sure why, I listed the material size on all my diagrams. I will live with it, because they did such a nice job. Just wish that the extra 45 lb wasn't on the high side for my center of gravity. I still have to add my supports for my racking. I figure that I will bring the weight up to around 200 lb finished and if I go roof top tent, that will take it to about 280 lb.
Is there any concern, if a gas strut fails or mount end failure, with this kind of weight? I sure wouldn't want anyone hurt.
PAToyota, I look forward to seeing what you create out of it, good luck.
