i have been using the porta chef for many years. i have it so i can cook anywhere on the site, or if i want i have it hoked to the line that would have fed the rvq. they are large enough for a family of 4 and is cheap at $100.00
We have a coleman road trip barbeque. They fold very compact and dont burn your food like many compact grill because you add water in a attached bowl under. When on sale they are a good choice for the campers like us. They can be hooked up to a 20 pounds tank.
We have a Coleman Roadtrip grill. It's awesome! We have the high pressure hose with it, so I can use my propane on the trailer instead of the little Coleman propane bottles. It's light and can fit a whole bunch of food. We love ours.
This is our portable grill, i am sorry but i just don't care for propane grills. A friend of mine ended up with 3rd degree burns and set is houe on fire from a propane unit. now what he did wrong i have no idea.
How big of a portable grill are you looking for? The one I have may be too big for your satisfaction. I picked this one up below at Academy Sports for around $100 on sale. It collapses down easily, but still takes up some space. The upside is it works great and I can cook a bunch on it at one time.
I usually take it on our campout/geocaching events and can cook up many hot dogs and hamburgers at the same time, especially after I modified it to accept 2 grill-dog rotisseries. I've cooked 4 big steaks on it simultaneously with no problem.
I agree with Kirk though. Charcoal sure beats gas for taste.
