I personally like the K over the G but I think Winnebago did a nice job on both. I was just at an RV show yesterday, and saw both. They've made some nice improvements over the past few years in the Travatos. (Some say Travatos, some say Travatoes)
IF you still have a coice, I would seriously consider the K.
I like the rear bath in the K and the aisle you can walk up at night... (they stole my design! > )
At the show, lots of people were really liking both models!
Enjoy yours, & welcome!
KOV... I'd rather deal with the KOV than the GOV! Check out the differences in the link above.
I like the "G" much better than the "K" because it has additional forward-facing seating for two, and a second bed up front good for a couple of small children, or one adult. The G also has better layout for carrying bikes inside in my opinion.
