I was in the same boat (pun intended) as you a month ago. The tally so far. . . $4,307.23 per my wife
. I still have a ton of stuff to add. 1st in line I think would be the wheels. You don't want to be dragging that beast on the ground to get to your truck or the water. I have a suburban, so I stuffed it in the back for the first few trips, but it sticks out almost enough to require a red flag tied to the stern, not to mention I had to keep most of the windows open because the exhaust fumes come back in through the tailgate. I went with a Yakima rail grab with Hully rollers and aero saddles for the roof. Works well for now but is a bit of work for 1 person. I have no problem loading in the morning, but after a day of fishing, it can take some effort to get that thing back on the roof. I may get a trailer at some point, but it sure is nice being totally mobile. I have a few fishing spots that have trailer and R/V restrictions. I am the only one that can launch from there. After that they sky (wallet) is the limit. My recommendation (actually one that was given to me on this forum) is to add things slowly. Don't make decisions in the garage. Get on the water and do a temp mount if possible to see if it works. It is big as far kayaks are concerned, but you still are in a confined space. See how comfortable you are getting up out of your seat and moving up to the front hatch. I think, on average, I have spent 10 hours of research at least on every add on I have done so far. Take your time, and it will fit like a glove.
Note: As far as weight. . "Memory Maker" is correct. It "is" 88lbs stripped, but you when you load her up and drag her to the water, you are at 140+.
