gas, electric, or charcoal grills

Get a charcoal chimney and you will be cooking in 5 minutes. If you don't use charcoal its tasteless. Might as well cook under a broiler, or on the stove.

I really enjoy both charcoal and propane grills.

Charcoal when cooking something slowly, or patiently. Gas when I don't care about the heat but want something cooked without fuss.

Watching for the smaller Weber kettle to go on sale. The full size kettle I've been lugging around takes a lot of space and there's no good way to tie it down, it's really top heavy.

It depends upon how small, compact, and space-efficient you want your RV equipment to be.

We have found the best at the above to be this one: https://www.amazon.com/Weber-1141001-Go-Anywhere-Gas-Grill/dp/B00FX3MH1O/ref=pd_sim_86_6?_encoding=UTF8&pd_rd_i=B00FX3MH1O&pd_rd_r=P15QC00NEH5KHAA74BMS&pd_rd_w=ktyTu&pd_rd_wg=j6cc7&psc=1&refRID=P15QC00NEH5KHAA74BMS

When closed up tight, a couple of the 1 lb. propane bottles can even be stored right there inside held tight between the lid and the grill. It of course has a built-in pizzo-electric starter, so all you need to do to BBQ is grab the folded up grill and take it to a flat surface, open it up, use the built-in hooks to clip the lid to the back to block the wind, screw on one of the propane bottles stored right inside, set the regulator dial to "start", and hit the igniter button.

Our RV even came with a small table that can be clipped onto the rear bumper for holding this compact BBQ if we don't want to use a free-standing outside table.

We also bring along a full-size a propane firepit so we can sit around a warm fire to roast stuff in fire-restricted areas.

This.

All things being equal, propane will be the most useful - you will be able to use it when campfires and charcoal grills are banned and when electricity is not available.

The others would be an option for me ONLY if I didn't like propane grills (taste preference) because they are more limited in use.

I carry both but if I only had one it would be a Weber Q 1200.

Oregon State Parks has been under a burn ban...no campfires, no tiki torches, and no bouquet grills.....propane is still ok...
Electric is available may require a long extension cord...
Just a thought.

Small Weber Q has worked for us.

I bought the below grill because it stores in a bag the size of a shoe box , it fit in my previous TC and its super light. Been using it for 10 yrs.
I use an EBBIT foldable grill with charcoal or wood, very small and compact. It stores in a very small canvas bag and only takes a minute to set up. I line it with a piece of tin foil for easy clean ups. Good for 2 people and will cook a large steak, four/six burgers.

It can bought at various places for various prices. I got mine at an Orvis fly shop at a clearance counter for $30.

This is what it looks like:

I don't like to wait on charcoal to cook A steak, or 1 chicken breast, so I bought a small gas table top grill, at WalMart, Very cheap, but works very well, have grilled steak, chicken, brats, hot dogs, & with a griddle on top, have done bacon, eggs, pancakes, French Toast & anything else I want to cook.

Weber Q series is probably the best of the best.
