Hi Fraser - First, thanks again for your help. I did see the 6'x8' figure in the set up instructions when my TRX arrived, but with your help, I had the whole shipping time to plan out the layout while my TRX was getting shipped. (I tend to 'ovethink' things LOL) We have now got it mounted...

Fitness Anywhere actually sells anchoring solutions for just such a problem. I weigh 220lbs and love my X-Mount .
