You have to tell us your riding area......
I ride with a friend in WV with a raptor....fuel consumption is ok........any quad will suck less the more you baby the throttle.....A tank is always an option to expand
Grizzly 700 - is a bad ass 4x4 you have a lot more options regarding fuel/camping equipment because you have racks.....the power, speed, and versatility is there....going to be a lot more comfortable for the long ride
A banshee will suck gas all day everyday....a big tank will be a must option for you wishing to go far.....six pack rack with a small fuel can will get you more....
The weight will be hell on all suspensions except the grizzly....the utility is designed to carry the weight...
But if its dune riding...woods riding....mountains...all of the above.....depends on what will be best for camping......if your camping with it a utility is the way to go.....I have a Big bear 400 for riding in WV.....you just get your ass kicked on the sport quads after a few hours of riding....
