Re: builds and sims that should be shared by maxis.
Most of them are in the Gallery plus a lot of other Maxis made sims and builds. There are TS4 versions of a lot of the TS2 and TS3 premades there too. You just need to search for them by using the EA Account ID of Maxis. Although, you are right that some of the trailer sims are not there. I agree with you and would like to have the ones that weren't placed in the Gallery by the Gurus like the girl in the Eco Lifestyle trailer but most of them are there.
Hope this helps.
