I have two different setup depending on the distance I'm traveling and the expected road conditions. First is my chevy pickup with a 6-1/2' bed and a canopy. I bought the canopy years ago for $500. I put the bike hitch on the receiver for my mountain bike and coolers/totes in the bed. I have a folding pad that's 3" thick for sleeping and small propane heater for cold nights. If I'm driving a long distance and the roads aren't a concern I steal the wife's Subaru outback and put a thule on the roof rack, it has a 2" receiver for my bike rack as well. I can sleep in the vehicle/bed and be more mobile for hunting. In the winter I will pack a 10x10' pop up canopy for getting out of the weather. Breaking camp takes minutes and I usually spend one night in the woods and one at the vehicle as I'm moving around. I like the idea of a big camp, but being mobile and able to relocate has been very pivotal in my elk hunting success.
Once I'm away from my rig I use a hybrid system depending on the weather conditions. I have a Borah Bivy, 5x9' flat tarp, a SO Silex, 12" LO cylinder stove, 30 degree quilt, synthetic puffy pants and hoody, insulated Nemo pad. I can run down to 20 degrees comfortably and the backpack camp runs anywhere from 3.5 pounds to 8.75 pounds depending on the weather/season.
