I have a 2018 Wolf Creek 840 with the Arctic Fox landing and I tow a trailer with it as well. Haul it with a 2009 F350 V10 crew cab standard bed.
I use an 18" hitch extension, and it's just cutting it. Your trailer may do better than mine since it has a 1' high support wall all around it, so in tight turns the trailer can actually bump into the rear camper jacks.
I installed the Torklift frame mounted tie down, fastguns and Timbren SES. Went with the Timbrens since they only engage when you are loaded, hated constantly adjusting my air bags depending on load etc.
