I tried making a light pole using 3 10' sections of 3" or 4" (I forget) The couplings are a definite weak spot. The pipe is threaded at that point making it weaker and the connection just isn't very rigid no matter how tight you make it. We ended up welding the couplings just to keep it from flopping around. I wouldn't trust putting anything substantial up there without reinforcing the joints somehow.
