Driving with landing gear partially extended?

I tried doing a search on this but only found stuff on landing gear that doesnt answer my question. So, I have a torque 301 5er TH and was wondering about this. If there ever was an emergency and the TH disconnected from the hitch wouldnt it prevent major damage to the TH by having the landing gear partially extended or even fully (not that I would do that). I know the breakaway will apply the brakes but the front of the rv is going to drop and have some damage without a doubt especially at higher speeds. There is no way the gear is going to catch something in the road being extended a little bit. I have an andersen ultimate aluminum hitch by the way and absolutely love it! I have safety chains too but Im working on getting a different way to cennect them to the bed cause my Ram came with the 5er prep and the hooks are squareish. The safety chains dont connect to the hooks without adding something in between. I have to remove the ends and put different ones on. Here are pics to explain:
