I would like to have side boards, but never have had them. I have some decent load guides that do ok. I am able to usually get the boat centered close enough. With C-Traveler, if I'm over to one side or the other, that puts me over the fender with 1/4" clearance. Tight! Any higher however means that difference needs to be made up in launch depth. As for bunks, Midnight Flyer came with only 2. I didn't feel that was enough, so I moved those bunks towards the outside, and then placed two more on the inside that were a little bit longer. There was a roller under the bow, but that was only for loading, and did not support the boat at all while out of the water. (It had a few inches of clearance from the hull once the boat was out of the water.) C-Traveler has the two main bunks that run from stern to about the front side windows, then there are two "targeting" bunks. I do have the targeting bunks set up to also support the bow, however they do not have the brunt of the bow's weight on them. I think they share that weight with the bow stop roller. The difference in trailers is that C-Travelers bunks are much heavier 3x9 boards and are up on edge so provide a lot more support than the 2x4's that layed flat under Midnight Flyer. All things considered, I liked Midnight Flyers EZ-Loader trailer better then C-Traveler's Karavan trailer. But that was after I did some mods on it. Not much I can do with the Karavan. Colby
