Emergency Exit Window Replacement

 

I have not done this, however, as you seem to indicate, it looks to be fairly straightforward.  Two persons would be ideal, I think.  My 5th wheel neighbor replaced his, due to a leak, alone by duct taping the outside piece of the window to the exterior and then screwing the inside portion to it.  There are some tape-like adhesive/sealant products that can be applied to the frame, prior to the install, which might make the job easier.  Good luck!

 

Note: This would be replacing the whole glass and frame as a unit.
