We were hanging out on our 21ec the other day and I was snoozing on the engine box cushion with my legs hanging off the back. Now I have a 5 gal bucket on the boat ad 2 smaller 2.5 gallon buckets from HS. My wife (ms. can't leave anything alone) got the 2 side cushions from the Vberth, Put the 2 smaller buckets on the step below the read seat and laid the 2 side cushions from the engine box cushion to the back seat, fit like they were made for it, and now I had a 6 ft bed. My thoughts are to run a small rail across the back seat upright wall (the buckets are a little tacky), strengthen the back on the cushions and I have some more laying around room
