Hi did you ever find a solution, I am also around 380 lbs and looking for a portable solution for me and my monkey bike. I have made various stands, some accommodate two hammocks one even three side by side, I have various portable stands for the van and the lowest weight I have gotten down to is about 40lbs but that holds my weight no problem and accommodates both my gathered end hammock, my Amok Draumr XL but as yet I’ve to find a solution for my motor bike. I have looked at the tensa solution but it’s too much money to modify straight out of the box and requires more than one anchor point for my weight. If you have any answers I’d love to hear them.
