We have the sister, Hemi 272RLIS. No good solution. I'm currently just eating space in the front, but plan on installing a couple of 5" plastic fence post for storage of the sewer and power cord. Plenty of post on the forum regarding the "fence post sewer holders". I may just go with 3 and make one for the water hoses as well.
