Basically did the same in our 5er. Put a 40" tv, sound bar with wireless sub, new recliners from Besthomefurnishings, took out the booth and put in a free standing table and two chairs. Have an XM docking station and a Winegaurd X2.
Still have two bikes and two kayaks we take when possible.
AT 65 and 62 we've slowed down a bit but still would rather be outside than inside. When it's inside time we have it as nice as we do at home.
FWIW we dry camp most of the time. This year will be the most non dry camping we've done in 7 years. Not because of needing to full hookup, but because of our destinations.
Call it glamping if you want, I'll call it comfortable. :)
Ironically we rented two movies to take with us for 4 nights over Memorial Day. Weather was supposed to be crudy for half of the time. Turned out nicer than predicted. Only watched one of the movies. Tried 3 times to watch the other one, but because it was nicer out we spent more time out riding the bikes. When it came time to resume the movie we only made it about 30 mins and fell asleep. Sucks getting old.
