Absolutely! You're only talking 6" on each side, you can frame that up plenty strong.
You can build it a variety of ways too. You could build the wheel wells inside if you wanted it to be frame level, and put a skinnier mattress, and you will still have the extra interior room to maneuver, and have some side storage, and will make it easier to change the sheets too. Just another thought!
