Don't know what you plan to do to trailer, but reading your reason to get in a TI after going boatless <shudder!> for a while, one of the best "accessories" worth investing in, IMO, is a tandem kayak or canoe trailer customized with the cradles for your TI, and the fitted TI cover. The ease with which you get on and off the water is directly proportional to the number of times a busy person will actually enjoy the boat. I think the formula is something like (FUN / AVAILABLE TIME) x HASSLE FACTOR = RETURN ON BOAT INVESTMENT
We bought our 2013 TI used, and I looked at every sort of cheap used, jury-rigged trailer option before giving in and investing another $1200 for a custom trailer. But the ease of setting up on the trailer and pushing off at the launch ramp, then reversing when we come in eliminates the hassle factor exponentially -- which of course not only adds to our enjoyment but also encourages us to get out often. Michigan summers are short, so we take the opportunity for a sunset sail after work whenever we can. We back the trailer down the ramp and slide the boat right in, and simply do it in reverse when we're done. It slides right onto the cradles, well, like it was meant to be there.
We keep ours parked full time at our local Yacht Club, so when we can sneak in even only an hour or so to set up, sail, and stow. (We do bring the Mirage drives home every time, along with seats, paddles ... anything not fully stowed under the cover.)
I look forward to hearing how much you enjoy this boat. We've had ours a year, now. It's honestly been one of the most enjoyable investments we've ever made.
