You are correct. You stand the chance of bending a leg or legs that way. You should raise the gear until the legs are just clear and then use the brake manual level to engage the RV brakes. This actually does two things. 1) it makes sure that the fifth wheel connection is secure and 2) it makes sure that the RV brakes are working.
By raising the landing gear just until clear of the ground it would allow them to catch the RV, and prevent damage to the truck, if the 5th wheel connection weren't completely engaged.
