not exactly the same sizes but i have a 20' (+5ft V) aluma. I carry 2 153's and 2 141's with room to spare. I pull them in from the front to the back all one direction, so the last sleds track sits in the narrow V.
If i put one in backwards, there would be even more room.
it would take a little work but a 20' would work. 22' would work best.
the 7' wides are the way to go. Like mine alot.
