RttToEE isn't a dungeon crawl?
Wow!  If they don't like RttToEE I can't imagine many dungeons that they would like!  And who doesn't like dividing up treasure... oh well... See if you can get your hands on "Castle Greyhawk" which features hundreds of rooms and encounters and is strictly dungeon crawl...  It is 2e tho, so you will have to convert it.  The Undermountain Boxed sets were also Dungeon crawls, but they weren't totally fleshed out, which can be a good or a bad thing, depending on the amount of prep time you have.  
I tend to like roleplaying to hack-n-slash because my players tend to cheat or fudge things in hack-n-slash, which, needless to say, causes problems.  That's not to say we don't do it, but I like to make them problem solve, in addition to swingin' the old broad sword...
fwiw
