Try this link to the Grand Design forum I use. There was a long discussion regarding return air icing up because of ducts not sealed at the start of the ducting at the air conditioner. Great tutorial on page #2. If you have two air conditioners, check them both. I'm assuming they will be the same between the brands. I think these are Dometic air conditioners. I checked mine and fixed a couple small gaps, but some members have had large gaps that's causing it to cycle on and off.
Separate issue: On air conditioning mode, mine also started cycling the fan on and off last trip, and I had to switch the fan to Hi or Low instead of Auto to stop it. Then later I would go to auto and it would would fine again.
