For sure on the Keel Guard. After fishing LOTW a couple times last year without air ride seats I wish I would’ve done that in my glass boat.
I know some guys swear by the drotto but I’d spend my money on other stuff. With a bunk trailer I don’t think you need one. I load and unload by myself all the time and once you figure out the right depth it’s easy with the bunks.
If you are fishing those bodies of water you’ll likely want some type of rod holders or track system if you don’t have it.
And a real good cooler….
^x2 The drotto has it’s place, but once you develop a pattern and experience with a bunk trailer it isn’t worth the money. I load/unload mine just as efficiently without as I would with. Roller trailers may be another story.
Everything else mentioned seems spot-on, especially the keel guard. My only other advice would be to start without thinking you will buy “everything” you need ahead of time. There are certain items that some people use and not others. Hit the water a few times and you will know. I’ve got quite a few fishing buddies with a lot of costly accessories and set-ups sitting in their garages collecting dust. One has a talon on his boat that I’ve yet to see deployed in 3 years
