Welcome to irv2.
Here is a
Brochure and
Owners Guide for you.
Below in my signature are links to many more for your coach.
If your talking about the engine dog house hump over engine to the right and on floor level you may have a black flat screw head. if you go outside with a flashlight and look under coach in that spot you will see the latch that you will have to turn to release so you can lift the dog house.
May need some flat spatula's to push down between the floor rug and DH so you can lift DH up and out from under dash board, its very tight.
Not sure which chassis you may have
Ford or
Workhorse.
