My opinion only...so you'll go from 3/4 inch to 1 inch (being your cutting a 2 inch in half) you're only going to gain 1/4 of an inch. Not enough to mess with.
I don't have best answer and looking forward to replies. I've also been trying to think of something better. I keep coming back to some type cover when parked. When actually using it, the gutters get cleaned out enough going down the road IMO. I also double check and make sure the caulking is good where roof meets up with on gutter.
Subscribed, someone has to have a good fix for "quality" RV gutters.
