I picked up a Cabelas ladder on sale a while back for my tracker grizzly, it didnt really fit well on the gunnels. The nice thing is Cabelas is always good about returning stuff... I ended up paying a bit more and getting one made that would fit perfect and could also be secured to the t-track. Its amazing how much they flex with a wet 80lb lab climbing up them...Check Mack's, cabelas or bass pro. They all carry hang on style dog ladders. Wouldn't be hard to make one up out of wood either...
