If it were me, I would not load the PA-14 on top of a Camry due to the "heft of the beast"
Aside from the overall weight, its also too easy to damage your car if it slips while placing it on the roof rack.....and the roof rack would really be at the max rated load.
The PA-14 is 38" wide and has "raised rails" to contend with if roof topping.........a trailer is really a much better option and you can leave your seat, any gear/equipment mounted or installed inside the PA.
My 2013 PA-14 is close to 175 pounds loaded with all of my things.....includes 4# and 6# down rigger balls, 2 SLA batteries, anchor ,tackle, etc, etc, etc. I carry my PA on a Hobie Trailex Trailer.
