Actually went to look again and found out that the 2318G has more storage room as the 2280 dinette has no storage at all in one of it's dinette seats and is screwed closed to house converter and other wiring.
Also the one storage area over hot water heater is just a silverware drawer as the 2318G is a large and wide storage area. So the 2318G actually has sightly more storage. So I'll be going for the 2318G.
The pic and video are 2018s, I'd be getting a 2019.
Here's a pic from Rockwoods website of the 2318G
