the other advantage of the trailblazer here will be its HEAVIER, than the pilot, and weight is your friend towing, also in stopping and even on snow, and winds, will less hectic I think in cross winds while driving
MPG"S, well ??? your at a disadvantage there I am sure due to again the weight and more HP/torque that allows it to tow better!
Honestly here,
and not bashing your options
if you have 4 guys going, I'd try and get one of them to tow with a bigger truck, and have a safer run, 4 door trucks are pretty common these days, got to be about 25 of them as to a basic 2 door truck in my area if not higher !!
a simple snow storm(were snowmobilers) can be a bigger issue in a smaller vehicle towing such a big trailer, and a simple slip off the edge of the road could make a trip into a rescue over a vacation!
I base this off 30 yrs of towing in winter time, but I also live in an area with a ton of up and down steeper hills,
twisty POORLY plowed roads, and having to pull up on up hill grades with unplowed roads or just lots of snow
I think you will struggle BAD, in conditions like this in my area
I know guys with trailblazers, and jeep Cherokee's that struggle with 4 place open deck trailers!!, and even some with 2 place clam shell's here!
but your call!
