my bed is pretty crusty so thats why I'm considering the 54 bed. I like the look and the mix and match doesnt bother me. If the price is right I'll do it. I'm just really having a hard time getting an answer if it will work.....Someone stated that the beds were bigger in 54....is that possible??????????? the hump on the 53 is much taller than the 54 so I dont think the hump is going to be an issue. Dont know!!!!!!!
