In June I'll be towing my 2000# 175 runabout from Texas to Michigan and back. My trailer is a single axle without trailer brakes. I've greased the axle bearings and lubricated the leaf spring bushings. The tires are radials and new, including one spare, inflated to the max psi of 50. The tow rig is a 2024 Land Cruiser. I plan to limit my highway speeds to no more than 65mph. I have the balance of the trailer setup so that the tongue weight is ~250-300 lbs. Lights are all in working order, and I will periodically retorque the lug nuts. Boat straps are all in good condition, and I have trim ram spacers as well. I just replaced the bunks (which were rotting), and there is no signs of corrosion on the frame/axle/springs. Of course, all gear and seat cushions will be secured within the boat. I was thinking about getting a second spare given the length of the trip, and possibly an anti-sway bar, though that may be overkill for this size of boat/trailer. I know that a double axle and trailer brakes would be better, but that isn't really in the cards, and the boat is quite light. So far, I've had the trailer on several one-hour trips and one 4-hour trip and the setup performed very well without issue. I plan to drive defensively, keeping ample space from other vehicles, and keeping an eye on side mirrors to check for flats. Does anyone have advice for other things I should have in preparation for the trip? Or things I should do/watch out for while on the trip? Thanks
