A top deck eliminates the fenders being in the way but also means the loading angle is significantly steeper so the advantage is a little less dramatic I guess you could say. Also it takes more winching power to load a vehicle on it than a standard trailer with ramps, because it's pulling uphill the whole way instead of only pulling one axle uphill at a time. Like normal
Car trailer half of car going up ramps while other end is on flat ground, then front is on level trailer deck while back end goes up ramps. Much less drag that way. Just something to keep in mind. The 10k winch is really freaking stout. I've lugged it but usually only when trailer batteries get low. I don't think I'd get anything smaller though. Smaller winch ends up getting overworked and that will result in early death. A heavy duty snatch block is a must. I don't need it for adding pulling capacity but mostly use it to change the pulling angle when you can't get trailer lined up straight with load. I had to use it to thread the combine heads in a small maze around a couple of trees and will also need to use it to get the combine out of the edge of the woods.
