We made the switch about four years ago after we were on an early spring camping trip and the weather was drizzly and cold. They won't let you bring your own firewood in many of the campgrounds out in California because of insects so you have to purchase from the campground. Usually it's about $7-$10 a bundle and that lasts a couple of hours. They actually prohibited scavenging for wood on the ground but we did it anyway on this cold weekend or we would have spent $100 on firewood just to stay warm. Because of the rain and scavenging, most of the wood was wet and our fire was pitiful and smokey. Nearly wasn't worth the effort. I would have just gone in the camper and called it a day but we were the hosts for the trip and everyone else was tent camping so that would have looked bad. One of the coldest weekends of my life...
After that experience, I decided there had to be a better way. Searching on amazon led us to gas fire pits and we pulled the trigger as others have. However, we went one step further and also purchased an outdoor canopy with a mesh enclosure on the side walls. It's large enough to fit the gas fire pit and about ten chairs. What we get is a bug free, smoke free, rain free camping experience. Because of the mesh, it helps to hold the heat from the fire inside and it can easily be about 5 to 10 degrees warmer.
This has changed our camping experience entirely. We store the fire pit in the shower and an extra 20lb propane bottle under the dinette. It only takes about ten minutes to setup fire pit and canopy and we have an enjoyable outdoor space if we want it.
One tip to add... At campgrounds that have fire restrictions, it is important to ask the host if they will allow a gas fire pit or not. Most may but not all. Last place I was at they were fine with it, just asked that I raked the pine needles away from the fire pit.
