MTK is our number one selling tower. We have installed about 20 of these towers. DO NOT install per instructions.
MTK has a leg spread of 18", which means a ton of concentrated stress in one area. Even if your fiberglass is 3/8" thick, still reinforce with some 1/4" plywood to beef it up. This tower is a solid tower, but it does have front/'back movement and the leg anchor bolts are known to vibrate loose. Be sure to keep bolts tight every time you go in and out of the water.
If you decide to go with this tower and want some installation pointers, shoot me an email. Ill make your life easy.
