My 2KW HOnda Generator lives in the tailgate corner of my truck bed. I have a locking steel cables securing it there. When I need to use it I just pull it out onto the tail gate. My generator goes where I go haha...
My way of thinking is to keep the generator out-of-sight when not in use. My truck bed has one of those folding thick panel folding covers on it which also locks.
The tail gate is the perfect spot for me to use the generator. The trailer shore power cable just fits plugging into the 2KW Generator using a RV30A-15A adapter.
