I pull a Passport 282QB with an Equalizer and it works great. I think it's hard to advise without fully understanding the final setup and load out. Which honestly was something I didn't even fully grasp until after I had many thousands of miles under me with this trailer. My trailer has 3 huge storage areas in the absolute back of the trailer that are massive, (key reason I bought the trailer). I store several very heavy pieces of equipment back there, (which is the exact reason I bought this specific trailer), and after checking weights on scales found that it was getting the tongue weight way too close to 10% for my liking. Luckily, the engineers at Keystone seem like they thought of this as they put almost all of the tanks at the extreme front end of the trailer and I always tow with a full fresh tank. That's why it is always hard to advise with an unloaded trailer. The problem is the axles act as a fulcrum which create a dynamic setup where adding weight does more than just add to the gross weight of the trailer. Weight on one end of the fulcrum pulls the center of gravity towards the added weight creating a more complex impact on weight than the mere mass that was added.
TLDR - Where you put stuff and where the tanks are located could increase or reduce tongue weight slightly or dramatically and the amount this will occur will be extremely challenging to calculate in advance.
