If the 2015 crew cage is like the 2015 2-seater, it is not round anymore. It is formed much like the a-pillar on a car or truck.
That's a great idea. Can't believe I didn't think of that. Thanks!using the "lock n ride" holes in the bed may be your best option till aftermarket gets up to speed on the 2015s. Just run your power and ground leads under the box back to the bed hinges and then forward to the bash switch or how ever you are going to power them...the box will still be operational! That's how I ran my ran power to my flood lights on my 400 with the box mounted rollcage.
Cheers
