I think maybe a telescoping (trailer) tongue would do the trick ...
hydraulic? electric? pneumatic? That way the wheels stay under the load,
there's weight on the trailer hitch, easy to maintan, ... and so on.

Ok now dont laugh, but I have been thinking after reading the posts about
launching and retrieving a boat from a boat trailer. What would you all
think about a trailer in which the boat sits on a set of rails and the
rails
slides into the water to launch the boat ? The way I vision it is you
would
back the trailer into the water, but not as far as normal, then the rails
slides the boat into the deeper part of the water? Just a thought crazy I
know

thanks
