I agree,if it happens to be a radial you dont have the same choice,why wont they /the company take more time and let you guys switch it around,I mean is there a rush?And if there is ...is it worth the outcome of an accident.I will be honest,theres not been many of times when Ive actually used a feed -through...sure some trucks carried 5,6 even 8,but we used them more for a stand off/parking stand....with the other side capped.Now years back we had some type of problem with a 34.5 loop and for some reason it couldnt be switched or something,cant quite remember.I was a young Jy and suggested using a feed through....well that was ok for my bosses so we went with it.I thought I was really bright for coming up with a solution....to make a long story short the feed through worked,but only for a few hours....thats been so long ago that I cant remember why it failed,but it did.All I can add is that they do and can fail,so be safe.
