Changing out queen bed for two twins

I am possibly purchasing a class a winnebago adventurer tomorrow. I am picturing taking out the queen n building platform around water tank that is at head of bed then platform down the sides. I found some mattresses 32 x 79 that would be perfect. I know we will not have an aisle down the center but enough of one to get into bed.

My questions: is it difficult to take out the two end tables? Has anyone ever done this?
It is a 1999 32'. Us two gals want our own space.
