we have an 03' mobius and my dads finally considering letting usd run weight on top of the factory ballast, i want to assure him that the rear ski locker will hold up the weight of say a 350# tube sac, provided you empty it before trailering it, but our boat stays in the water all summer anyways so it wouldnt be a huge consern. does anyone know about the boats construction in reguards to supporting the weight for sure.
