Small vs. Mini for RV camper?

We have a new RV travel trailer and we will be doing a lot of camping over the next few years. I have a nice portable propane grill which I took on our first few trips but I just couldn't enjoy the food after converting to egg life nearly a year ago. So now I am looking to buy either a Small or Mini egg for the RV.

SIZE: We want to have a large enough grill area to cook enough meat for two people, plus at least one side dish such as beans, potatoes, carrots, etc. Doing an occasional turkey breast, pizza, or small pork butt would be a big plus but not an absolute necessity. Small has the advantage here obviously since it has a larger grill area and they don't even make a plate setter for the mini.

STORAGE: Our external storage compartments on the RV are probably not big enough to hold either of the eggs but we might be able to make and mount some kind of storage box on the front hitch or the rear RV bumper. Looking for some ideas here. If the custom enclosure doesn't work then I will need to haul it in the back of my truck which has a pretty large covered bed. In either case I want to protect the egg from the elements, bumps and shocks, and road debris while in transit. Mini has an advantage here because it is smaller and should be easier to store.

WEIGHT: Not a big concern for us since we have over 3,000 lbs. of capacity for gear in our RV and vehicle.

COST: Moderate concern for us. We can afford either one but won't use it nearly as often as the Large egg at home so we don't want to invest too much. Especially if it breaks in transit or is stolen from an unattended campground.

HEAT: In some cases we might cook on the egg and then need to break camp and travel just a few hours later, but in most cases we would let the egg sit overnight before hitting the road again in the morning. I assume the Mini would have a slight advantage here since it could cool down much faster and might be easier to handle when still warm.

ACCESSORIES: I assume we will carry about the same amount of supplies for each egg (lump, wood chips, utensils, thermometers, etc.) but maybe the Mini would have a slight advantage since it would not have a plate setter and takes less lump.

I would appreciate some feedback from those of you with RV campers or those that have traveled with eggs for tailgates, eggfests, demos, competitions, etc.

FYI: Best price I have seen on a Mini was $175 brand new, $100 used. Best price on the Small was $347 brand new, $50 used. The used units were great deals but I passed on them because they were too far for me to drive and pickup. Still shoppping for a better deal on both.
