wow a lot of tow vehicle info.
Forest River has the Rockwood Ultra Light,
Grand Design has the Reflection,
Keystone has Cougar, Laredo and Outback,
I think it is Forest River also that has the Cheerokee.
Go to the websites and check out each one and see what they have for weight ratings etc. Lots of them out there. Be sure to choose what will work for your vehicle, we ended up with a different unit than originally planned as the usability of some thing wasn't good for us.
Happy with our New Grand Design 303 RLS, now just to upgrade tow vehicle.
we looked a lot and ended up with a Grand Design. They make 2 half ton towable units and others they have may work out for your weight ratings.
Good Luck & Be Safe ! ! !
