I'm using a 24x48 no upright on my trailer now. It worked well, but for competition I like to use different woods for different meats. So we got a pit maker vault, but we roll that on to a separate trailer and haul it around. I wanted to put it on my existing trailer, but it won't support the weight. Wanted to add an axle, but it wasn't recommended. Thought about mounting the smaller pit maker safe on there, but I still might be pushing it. Weather I get the 24 or the 20 I'm still going to have a vault or safe mounted on the new trailer with a frame and axles that can support the weight from the get go. So I'll have large capacity capability if I run out of room on the smaller 20 inch offset. I just played around with my 16 horizon ranger which is 16x40 and I can fit two 9 pound briskets on it comfortably, so I think I can put 4 on a 20x60, but it's gonna be close and I'm pretty much limited to 9lbs and under which isn't always going to be available.... I'm trying to justify to myself for going with the smaller size since it's really just for competition and maybe a tailgate at the game...for cook offs I only cook 2 briskets and for a tailgate party 3 usually gets its done when I have other meats like ribs or butts...ill have the vault if I really need to load up for a large reunion or something...cooking at home, I'll still have my other pits for bigger cooks...im having a real hard time letting go of that gator...but, I know you guys are right... I should go with the bigger size... Maybe I can leave room and add a gator grill or something later on.
