HI there is a small compartment on the road side (left) just pas the rear wheel. it is about 10-12" hatch open that and look straight in there should be 3 pulls grey (galley) on the left black in the center Gray shower/washer dryer if equipped. hopefully they are labled correctly which still seems to be a keystone joke
this said i assume you have a fl 3750. Enjoy the camper we love ours.
i just looked at your profile and i see it's a 3750 the same as ours.
