Monster truck will be totaly useless. It will cost a high among of developing time and we only use one or two time. It's a RACING sim, do you imagine a race with monster truck on BL1 ??
For the suv i'm not for but why not, it comes more in the field of racing since we have cross races. Anyway there is a topic to suggest cars. It's a great topic, people come to post there wonderfull idea a milion time proposed before thinking its revolutionary and nobody care about it or at least read it
Would be fun to have a car like that in LFS, but still.. it would not fit in. There currently are only race cars in LFS, and if you put in a monster truck...well lol then it`s simply not fitting in any of the other car classes.
What LFS really need's is a auto-search-for-threadsubject-and-post-before-creating-new-thread-script. Then everybody will be happy and will post in the "Cars we want to see in S3"-thread instead of creating 3000 different thread's on which car they want in.
