If they are outside your rig (such as on the tongue) you have several options since they do not need to have an external venting system. I even found some nice ones in aluminum on some website.
If they are inside your rig (such as a 5er), your options will be much more limited. I ended up building a battery box setup.
Note that this just applies to flooded cell batteries. You can get away without external venting with AGM and Gel cell batteries, but the cost is significantly more.
