Jack, unfortuanately almost ALL gas generators are installed in this manner. They (mfg of coaches) try to use every available square inch and so cramp everything. This does make it more difficult and expensive to maintain. We use a floor transmision style jack to aid in this lower of these units and it is not as bad as it sounds. Good luck and be safe.
