specific A/C venting question

hi,
i've re-done the way my A/C is in my camper. I'm still perfecting the water-tightness of it. What I'm wondering is if I can block the front vents/louvers without hurting the unit? the other side only has the back set of vents/louvers.
INSIDE:
Thanks in advance for your help!!!
