Good carch on the milk crates, just ordered 2 for my propane bottles. They are a pita to get. I want some old metal ones for the toung, but they cost like 50 $$ a pop. As for the chairs, im tall and not real big (225) so im good with what i have. But i do see it as a concern . Most of my reguler chairs break within 2 years. The ones i got with the pup( 20 year old Coleman) chairs work well and held up great. There steal and heavier then the newer types. Reinforced at the connection points.
