Daing, as a long time triton owner I can definitely feel your pain with these loading issues on a marine master trailer as that's what triton had under their boats for years. Pain in the azz!!! My boats always wanted to come in left of the roller and then when I'd hit it center and get the bow eye up to the roller it would slide back down as soon as I let off the hotfoot. And try leaving more bunk out so the boat wouldn't slide back...forget it, it wasn't gonna powerload itself all the way on that way. Launching..? Had to pretty much back it down fast and hope it came away from the trailer before the bow had a chance to drop, if not, trolling motor would bounce right off the roller. And I certainly hope they junked the tube trailer idea. If not, give em about 5-6 years and they'll be half rotted out from the inside (keep an eye on the cross bars in the latter years). This has been like reading the horror stories from the triton board a few years back. I was told MM would say the same thing then...that it was driver error, so the problems were pitched back to the dealer (which mine always stepped up). Thankfully ranger (fish holdings) built the trailer that's under my current triton. I'd have a hard time buying another boat that had a MM trailer under it. I surely hope they work it all out for y'all caus i certainly know how it feels to love your boat but have a serious hate for the trailer it's sitting on.
