You might want to consider getting a memory-foam topper for the sofa. Costco has some good ones. We don't use the sofa but one of our Labradors does. He can sleep on the floor, so the sofa is fine for him as it is!
We got one of the Costco toppers for our queen bed in the MH and just love it. We're getting a second one for the guest bed in the stick & brick house on our next Costco visit. You could put a cover on it and stash it in a storage bay during the daytime hours. Much more comfortable than a basic rubber mattress.
There's so much to see in this country. We've lived here since emigrating from the UK in 1968 and haven't seen a third of it. We've lived in NW Washington state all but the 3 years we spent in Tidewater Virginia.
Hope you can make it to this neck of the woods on one of your trips. My sister, who still lives in the UK, reckons Anacortes is where God goes on his vacations. I'll post some local pics on here soon, so folks can see what it's like.
