Welllll, how particular are you? Doodles are nature's velcro.
We are on day 122 of our 160 day +/- meandering trek from FL to AK & back. When we left home our sweet Ollie looked so quaint. Matching bedding, pillows, rugs & I did my best to keep it that way. After a few weeks, I reassessed my priorities & ditched the fluff. The pretty entry rug was replaced with a plastic grass one to catch as much of the outdoors before it made its way back to the beds. (We have the king/dinette version but because the bed/table made the interior feel tight, we left it with family in KS.) We sleep on the benches with memory foam & the dogs get the space at the back & on a dog bed on the floor. That is where they hang all the time, except to drink from their water bowl that's in the shower. Weather permitting, we are outside most of the time, which I think is the norm. We mostly boondock but between locations we stay somewhere with full hookups & do a deep cleaning, laundry, grocery shopping, you know. What I learned the hard way is that trailers do not have enough water pressure to bathe the dogs. Groomers are impossible to schedule. If you know where you'll be far enough in advance, you might be able to schedule one at a Petco or the like. Otherwise, I find a do-it-yourself dog wash. Some places there are car washes with one bay converted to a pet wash. Quite clever!
Only restrictions we've encountered is hiking in National Parks or anywhere there are bear problems. But then, I wouldn't take them anywhere dangerous.
Despite all of the above reality, traveling with our Doods is a pleasure; they are the reason we have a camper. If you decide you need more space, I wouldn't blame you but there are huge tradeoffs. The obvious is the quality & comradeship you'd lose. Ollie owners are truly special.
