I was planning on upgrading the the rears on my 13 OBV with 750#. Simple plug and play upgrade there. I was wonder if it would be possible to slide the 400's under the bow seat one on each side forming a V.

I know I won't get them full. It would be cheaper then buying an IBS.

I figure the the rear sac (50x16x16) is only 2" shorter than the IBS arms (52x12x12) and I would lose a little bit under the front seat. But at the end of the day they will both only fill so much no matter how big.

Also, for those that run the IBS how much weight are you getting up there and do u still run the center 400#?
