We live fulltime in our 3600JS and at first I missed having the extra storage under the bed like we had in our Big Horn. Then when I realized that one side of the bed frame compresses when the slideout comes in I understood why we had no under the bed storage.
We use the single drawer to keep the bath towels in, works well since the bathroom is right there.
Being fulltimers, we need to be aware of our weight at all times so guess it is a blessing in disguise not have the extra under bed storage.
I do really enjoy the storage at the headboard, which is something the Big Horns do not have! Tradeoffs.
