Take off anything that you think has any sort of possibility of falling or getting blown off on the trip back. Luckily you're only 110 miles away and not driving across the country over 3k miles like I did last fall. Take all of the canvas off as well as any cushions, pop off hatches and basically anything else that isn't bolted/welded down. On my trip back I had one speaker fall off completely into the cockpit of the boat and the other was hanging by one screw when I got the boat back home, plus the push in hatches all blew off as well. When traveling at 70+ mph and there's wind on top of that, it'll push and knock things around a bit. The hardtop should be fine but I'd check any accessories that are attached to it, remove the canvas, the cushions, hatches and make sure everything else is secured or fastened down and tight before going back. Luckily you've got an aluminum trailer which is a bit lighter than a galvanized one, so that'll help with some weight savings, along with only having 25 gallons or so of fuel in the tank. I'd try to limit as much gear as possible in the boat as well as in your tow rig so that you don't add anymore weight, but I think you should be fine with your current tow rig's capabilities.
I also noticed on my trip back that the safety chain on the trailer that connects to the bow eyelet on the boat either got knocked off or someone disconnected it one morning when I left my hotel room to start driving for the day. I would check yours and see, but if it doesn't, I'd get the hook that has the clamp or return spring on it so that it doesn't come undone. Also, some good tie down straps as well as some basic tools like wrenches, a socket set, a lug wrench, jack, screwdrivers and whatever else you think you might need in the hopefully unlikely event that you have a blowout along the way back. I'd also make sure you check the brakes on the trailer as well as the bearings if possible and the tire pressures and all of your trailer lights. Good luck with the drive, be safe and keep us informed.
