This! ^^^^^^
32' is smaller than you think as a bunch of that is taken up by the engine and driver's compartment. Subtract that and you'll be lucky to have 25' of living space.
We've had 3-Class A motor homes (bus type) since 1986...26', 35' and 40'. In each we lost between 3-4 feet of living space due to the driver/passenger area. The advice to rent one, or more, of varying lengths, is great advice that you'd be wise to heed. RV'ing is a great way to travel but it's not for everyone.
Right now you likely have a romantic idea of what it will be like...the open road, crackling fires at night, seeing places and things that you've never seen, moonless, cloudless nights with a canopy of stars that will make you dizzy. And all of that is true. Also true...traffic, crowded campgrounds and RV parks, dumping your waste tanks, using the RV for errands and sightseeing if you don't tow a car, loud, sometimes drunk, neighbors partying late into the night and more.
Try this at home. If you have a room big enough or maybe on your deck, patio or back yard...mark a space 25' long by 8' wide and envision living in that with 4-dogs for multiple weeks. And remember, the actual space will be smaller when the walls for the various spaces, furniture and appliances are added.
Good luck. Happy to answer questions or provide advice as requested.
