We have a 42 ft coach. Is this too big for camping in Canada and Alaska? How about camping in the lower 48? We have been denied access to only a few parks. Is this typical? Thanks.
You'll miss out on fitting in some places, and some places only have a few spots you'll fit in, so if they're full you won't be able to camp there. If I were in your shoes, I wouldn't worry about it. Reservations will be your friend.
