My 28' TT is 5k dry. Fully loaded truck and all I expect about 6.5k.
I keep my camper in Java, VA and hauled it to Jordan Lake for Memorial day (500 round trip).
My truck is 2012 F250 6.7 Crew longbed fx4 with 3.31 rear. Hi&S mini max set to stock, egr and dpf are out.
14-15 mpg with the load and heavy foot. No load 20 mpg easy. Pulling a tandem jet ski trailer with two skis I was at 17 mpg.
Prior to delete I was 17 on hwy no load 14 city 12 with the camper.
My truck has 217,000 miles.
Check your driveline. Be sure your front hubs are free, drive axle is smooth and brakes are not dragging (parking brakes suck on this model) then check your trailer too. I think with that poor milage you have a problem. Might be dpf/Regen issue
