I have a 2001 Jeep Wrangler that I bought to drive my 2 boys (3 & 6yrs) around and they love it. We have their car seats in the back but I am wondering if there is anything I could do to make it more safe in case of a worst case scenario (also to make the wife feel better). We live in a small town so I'm not real concerned at the moment going slow (30-40mph) down back roads with them. I dont off-road so I'm not worried about flipping but at some point I want to take them camping and that will require us to get on the highway. Should I look into get a roll cage? Do yall think a straight across rear bar would add anything? Its seems Rock Hard has some great stuff. Any advice would help.
