Snoring dog in van

hi, we have a 4 year old king charles cav and we are about to embark on taking him on his first camping trip.. we've been putting it off cause he's a bad snorer to the point where he's not allowed in our bedroom due to the noise..anyway, any recommendations on how we can cope with this when he's with us? we have a 6 year old daughter who seems more sensitive to it than us unfortunately.  we are bringing our porch awning also.
