We have had the 3100RL for about a year now. We have lived in the unit for about eight months of that year. We have found the storage ok. We have also thought of a small island/table to extend counter space. Fireplace, we use every morning and thru out the day, during the colder months, propane at night keeps basement warmer. Last year during 105 deg, took both AC units to keep cool. I would recomend penguin unit for height consideration. With full AC and G615's we are at 13'5". We removed one of the recliners and the little end table. Replaced with little round ottman for the couch, also provides a small storage space. Added a wally world small desk where 2nd recliner was for desk and a small three draw plastic unit
next to desk for storage and printer. Works well.
