yes, everyone bad mouths scissor trailers, and if I was hauling a 'toon 300 miles, I would want a bunk trailer.
however my friends FUGLY looking crappy yellow painted $200 scissor trailer (price 15 years ago). makes a minimum of $600 every spring and $600 every fall taking 'toons in and out of a lake in Wisconsin every year placing them on and off blocking in peoples yards and drives. by my math that trailer is gleaming polished 24k gold.
no-one wants scissor trailers because they are a bit unstable at highway speeds, look like an erector set on steroids, and usually rusty as heck - just plain ugly eyesores. However they are dirt cheap, you can unload the 'toon anywhere
you missed the main point why I suggest a scissor trailer - to not only get the OP's pontoon out of the water, however to also make boat money on the side.
