Not a db guy myself, but I've spent time in some. You'll pay more for a wider boat, unlike a 48". Also check the trailers out. the two CL adds posted here both have rusted trailers. Galvanized will cost more, but will last longer... A good painted trailer that hasn't seen salt is also not a bad deal. When checking out a potential purchase, I'd take the boat off the trailer and look at it really well, even get on it and look for weak spots/flexing. That'll help spot busted welds.
You generally don't need to get your db trailer wet when unloading or loading your boats because they're pretty light. Getting a motor will also extend your fishing range quite a bit!
good luck,
