As you may have gathered if you have read any of my posts, I am a huge fan of the Q3200. But, if I were a tailgater/camper/cook-on-siter, I am afraid I would find myself shopping for a Q2200 instead of figuring out how to transport my Q3200, particularly if space is limited in my vehicle.
First, unlike the Q1200 and Q2200, the stand is required. The smaller Qs can sit on a picnic table, a pile of rocks, or even flat on the ground and be just fine. The drip pan on the Q3200 is built into the stand, not the base, so it is going to make a mess if you don't take the stand with you.
And, for travelling I think one of the coolest features of the smaller Qs is being able to use torch bottles. Not lugging around a 20 pound tank would be reason enough for me to give up the extra real estate on the cooking grid.
But, if you don't do it on a regular basis, and you have ample room in your vehicle, four bolts separate the grill from the stand. Pop those out, unhook the tank and transport it as three manageable pieces.
