So I was bored and decided to launch some random base to Duna when I discovered the service bay part. I thought "Oh kewlies I gotta use this somehow" and thus put some batteries, RCS fuel and stuff in it, the works. When I saw there was some extra room I decided "bugger it ill wack some seats in there" and IT was not until after I landed on the north pole and played around with the new base I saw the possibilities. free upload image The service bays could easily be used as little apartments or rooms for kerbals without any wacky mods! This excited me because I prefer to play without any mods n stuff and this tiny discovery means a whole new world of colonizing possibilities and ideas have been enabled. I'm gunna try and make some furniture out of the structure parts in other base now. Also (obviously) the door close to, I dunno, simulate a pressurized environment. Hooray for RP! Anyway I'm no Scott Manley at KSP seeing as my most valued feat is just getting a manned crew to Duna AND BACK but i just kinda thought this was cool...
