many will go thru the entry door
once you remove the fridge doors and any obstacles like seats etc..
sometimes, people go thru one of the windows,
removing the window frame and everything
bring the old out and the new in, laying flat
then replace window
depends on the particular RV
I can explain it to you.
But I Can Not understand it for you !
