Grille Guard on motorhome?

There is very little frame support in the front of a MH to attach a cow catcher like that to and in an vehicle accident will cause more damage then stop. It will work for animals and low speed bumps. The cap is designed to take a lot of the energy in a collision. Go into any RV body shop sometime and look at the damage and what little metal support is in the front. It's far easier to repair/replace a cap then repair frame damage!
