Fifth Wheel RV Living full time need advice

Hey guys. So, long story short we’re living with my parents in their 5 acre land and they have a fifth wheel RV in which my husband and I are currently living in. We’ve been applying for apartments and even my dad is generous enough to try getting a house for us;however, the housing market in Chicago is literally insane. Looks like it is not in our cards to live elsewhere by the time our baby arrives (March 5th). We’re trying to find best options on how to modify our fifth wheel for the baby, mainly for a crib and such. We have a queen size room and a bunk bed room and I believe our sofa can be moved/removed to make room for a crib/bassinet/play pen thing. It literally looks like a small 2 bedroom apartment. What are your guys thoughts?
