I am towing an 8324SB (front living room) with a 1-ton gasser. You have a 'dry' tongue weight 200 lbs. more than mine but similar overall weight and length on the 8000 series are all the same.
Pulling the weight is not the issue for me, even up grades. For me, I believe the length of the trailer is just a bit much in a bumper pull to achieve that 'don't even know it's back there' feeling. Even modest cross breezes make me very aware of it. I also have a shortbed (6.75') truck. In my posts here
and on other forums on my towing experiences with this trailer, many have commented that a longbed truck would provide more stability.
I have a 4-point Equal-i-Zer that is dialed in nicely but in my particular floor plan, I believe the lack of tongue weight (11.5% per CAT scale) + shortbed truck prevents me from getting a better tow. I found that traveling with a full FW tank and all other tanks empty, helps quite a bit.
Since you have a different floor plan and that extra (1320 vs my 1115) dry TW may, you may not experience the issues I have.
