I have been looking for a fifth wheel for quite some time a really like the Landmark. It is way better than the competion but I have one suggestion. I may buy a from the competition for only one reason. A real King size bed is 78 X80 but in the Landmark its 72X80. (most fifth wheels are only 72" bit some are 76X80) It appears there is room to put in a 76" wide matress...any way you could do this? Any plans to upsize so regular king size sheets would fit and people like me who want to spread out have more room?? (ya I know its only 4 inches and I am way too picky but it is influencing my buying decision)
