I like my Jeep.
I was in the same boat as the OP trying to decide on a toy car and out of the blue I just bought a Jeep. The hate flowed through just about everyone and I was cast into the depths of BC's basement for punishment since I would no longer be attending drag days. In the long run though, I really enjoy the Jeep and it's a LOT more fun with kids. I suspect your dogs will enjoy it just as well.
I agree with many others though, if you are 2nd guessing it, go drive the others and clear your mind. If you get the Jeep without even trying the others, you'll likely end up wanting to dump it later and may not give it a fair chance either.
