Yep...my shorty has no underbelly space left so I am building a little 24" deck full width on the rear. It will also have another 24" hinged section that folds up so that when docked I can drop it down and have a 4 foot deep, off the ground patio. The genny will hang on one corner with it's fuel tank under the deck. It will also be home to a spare tire that locks up underneath.
BTW...what is your take on this for a driver side, engine driven A/C unit?
