I have a 25' travel trailer that I pull with my 3/4 ton Suburban. I used to have a half-ton with a higher rear end and it just doesn't cut it in the mountains.
Just about everything in life is a trade off.
Last year I took our trailer to the Area 1 match near Puyallup, Wash., the Idaho Glock Championship and a couple of matches at Albany, Oregon. Except for Idaho, I was able to park on the range. My 25-gallon fresh-water tank and 40-gallon wastewater tanks were more than adequate. I have a Honda generator so power is never a problem. (My idea of roughing it these days is having to use the generator to power the satellite TV receiver.)
The best part was the camaraderie at the Area 1 match at the Paul Bunyan club in Puyallup. I met a great bunch of new friends.
My wife and I drove from Oregon to Phoenix for the Río Salado Area 2 match and did NOT pull the trailer (we're retired so time isn't an issue). I think we saved money by staying in motels, but I'm not sure. RV parks aren't cheap these days, although you can spend the night in the parking lot of most, but not all, Wal-Marts while on the road.
Comfort and cost increase with size. Mobility and gas mileage of the tow vehicle decrease as the size of the RV increases. The larger the vehicle, the more attention you have to pay to such details as changing lanes on the highway, access to fuel pumps, campground spaces and going down roads where there's no place at the end to turn around.
Motor homes, unless you pull a vehicle or have a mobile friend, are a problem since you cannot easily move to go the store, match stages, etc. Truck-mounted campers have the same problem.
I wouldn't purchase a trailer just for matches, but ours is used for other purposes as well.
Good luck
