I don;t know if this is an EZ brand- it should fit a wheel with a 245/75R/16 tire mounted- but check with seller- you will also need to check bolt pattern spacing as he has a MB
( on some carriers the bolts for the lugholes are somewhat adjustable)
Roadtrek used a 2nd 2" receiver similar to the hitch receiver offset for the mount.
Maybe this will work for you- I really like the added brake light as i know that some mounts block signal lights
also check your local classifieds- craigslist will have a wheel and tire section and also auto parts- check both
did you check roadmaster ?
