Any GI Joe 3 3/4" vehicles fit in with CH?

[Grand Slam]

My 3 year old loves the Combat Heroes, more than his 3 3/4" figures. So we've been using a few of the vehicles/playsets when we play with them. I've found the Quickstrike and DTC HISS Tank to be decent. They're really no worse than the SHS or GH vehicles as far as drivers, they pretty much just lay in there. The Joe HQ and Cobra Mountain work really good, but I really want to get the 83 Joe HQ at some point, my favorite toy as a kid. Here's a few craptacular pictures to show what I mean. So anyone else got any other suggestions for vehicles?

Hey those DO look good with the DTC HISS! I'll see about digging out my Joe vehicles sometime early next week. And you 3year old likes the Combat Heroes more than the 3 3/4" Joes?!!! You have a very intelligent child! I recommend placing him in a gifted program as soon as possible

Wow nice. Bases are the coolest. I've been on the lookout for stuff that might work for my Heroes, but haven't come across anything so far.

The Mini Zartan Swamp Skier that came with the 25th 3 3/4 figures works better for Combat heroes than it does 3 3/4 IMHO. Good item to look for.
