WHAT SIZE DO YOU NEED FOR YOUR BOAT/RV?
The manufacturer’s size is not the true length of your boat or RV. Be sure to measure from end-to-end. Start from the hitch and measure back to the rear bumper, spare tire, or ladder to get the true length of your RV. For boats measure from the trailer hitch to the farthest rear point when the motor is in its stored position.
Storage spaces are in 5ft steps (15ft, 20ft, 25ft, 30ft, 35ft, 40ft, 45ft). After measurements round up. For example, if you measure 26ft you will need a 30ft space, it will not fit in a 25ft space.
