Just my 2 cents,but I would not tow a 35 ft trailer with a 123wb SUV,especially if all my family is onboard.You will be overloaded,get terrible milage and be riding on P series tires.You are in 3/4 ton crew cab territory.

12mpg with a gas engine towing a high walled TT with a gas engine? Never heard of that. Budget for 8mpg, might get up to 10mpg. Fact of towing a sail, brick, whatever through the air at 65mph. 12mpg for a diesel towing a TT, maybe.
i was only posting a range.
with ideal conditions, someone can get 12mpg for a period of time. i wasn't posting an overall amount.
heck, a guy on another RV forum claimed nearly 14mpg on a 90 mile drive, with his F-150 5.4 v-8.
no one believes him but he claimed that he had ideal conditions and it was true.

Too many variables involved. On big heavy 35" mud tires I average 200 miles per tank. When I had 33" A/T tires I averaged 250 miles per tank. If I go much above 65 mph it seems to reduce another 50 miles per tank. Either way, for me towing the TT seems to kill about 70-100 miles per tank from when not towing. Heavy winds make a hige difference, my awning got blown off while driving though some very heavy gusts on a storm front a couple weeks ago.

Figure 8 for your budgeting and go from there. You are not going to get anywhere near 9-12 as someone else suggested. You will get 9-10 on a good day (no wind) and 7-8 on a bad day (windy). Guessing you will average 8.5 overall for a long trip.

I agree. I also think that 9500 GVW trailer is a bit large for your Armada.
The hills in W.VA maybe unforgiving. Beware.

I towed a 2008 Hornet 30BHS for quite awhile an 07 1500 Suburban 6.0/4.10, and usually average 7-8 MPG towing through the flats and moderate hills of Missouri. Before that, a 2006 Fourwinds 28G (with slide) towed with an 06 Yukon 5.3/4.10. Same mileage of 7-8 MPG with that as well. So, there seemed to be a pattern 8 MPG on average. Probably will be the same as your Armada. I'll spare you the lecture on being over GVWR, as I probably was as well. :-)
I get 10-10.5 with my Tahoe pulling my Passport 238ML. I've seen 8.5 in all stop-go traffic. I get 10-10.5 whether I'm pulling at 50 or 60 mph. With your bigger rig I wouldn't expect above 10.
