Deer Slayer,
One of the things I have noticed with Alumacraft is that a lot of the dealers utilize "Eagle" trailers. I've seen other identical boats to mine that have been on other trailers and they don't load nearly as easy. Both of my alumacraft's sit on Eagle trailers and everyone I have been with has commented on how easy they load. Part of it has to do with how low they are in the water, the slope or angle of the trailer and so on, but I don't back up any more than anyone else.
My competitor takes one hand to load (not kidding). My dad has a bad arm and shoulder (almost limp arm) and can load my boat. The same with my Fisherman. My buddy has a fisherman (16 footer and identical to my little boat) with a shore lander trailer and he hates loading it. Nothing special on the eagle trailer, just a bunk style.
Trailer makes a ton of difference. If you like your boat but have hard time with the trailer, might be worth upgrading that instead of the whole boat. Heck, I'd be willing to let you put your boat on my trailer and see how it works. I'm sure others would do the same if the launch isn't all that busy one afternoon. You might be surprised!
If a new/newer boat is in the works, you are starting out right by asking people specific questions. I would say to look at several older and newer models and find what you like about them. If storage is a big issue, keep that in mind and don't settle for something. I have always purchased my boats new but I like to look for leftover stock. My competitor was a brand new boat but a 2013 instead of a 2015 (identical boat different decals) I save over 10 grand.
Also, be willing to drive someplace to get what you want. Michigan has tons but I've looked in North and South Dakota for buddies before!
