So if you only have the f3800, it’s a 5/5, BUT, and this is a big one, if you have expansion battery it doesnt have a zip or velcro in the right place on side to let power cable stick out and not long enough to go over battery and f380. So it’s a 5/5 with just f3800 BUT really a 1/5 if you have expansion batteries. So I’m putting 3/5. It does have zippers in the corner but not centered where it would plugin

ill let you know when it gets here

Appears to be well designed and high quality. Functionally has good access to controls with expanding sides to allow space for cables and ventilation. I’m impressed with this product as I plan to use the unit outdoors for RV backup power. Looks like it will be well protected with this cover.
