I like the oil heaters but they take forever to warm up and cool off
and they weigh a ton.  I have found that the ceramic heaters are quick
to heat and actually do so much better for the weight than the oil
based.  The oil based are much better to use a house to keep a cold
room at a decent temp.  

If you do not use your ceramic let me know the what you want for them
and could you post a picture.

From the years of reading posts here the problem would be cost with
having a heater put in. Not only the cost of the furnace but the cost of
propane. Two ceramic heaters can keep us plenty warm even if it gets to
freezing and only costs $40 for both of them. Of course if the
campground doesn't have 30 amp electric you can't run them both on high
at the same time and if you are boondocking you are screwed. Just my .02.

Nice rig.  Nice camp site.   :)

You aren't a TRUE, high-tech redneck (oxymoron or just moron?), until you
place the TV OUTSIDE on the picnic table under a canopy and watch it with
drizzle all around.

I would like to see a new option:  Built-in electric heat.  Sure, it wouldn't
run off the battery but neither does the air conditioner or microwave oven.  
The biggest downside to a portable heater is the floor space it occupies.

In the 13 years we used our Starcraft, I only used an electric heater a few
times.  The electric heater didn't put out enough heat to keep us
satisfactorily warm on some of those occasions and it took up precious floor
space.

I paid for the furnace, so I used it.  We once camped when the overnight
temperature fell to 13 degrees F.  We used a LOT of propane, but we stayed
toasty and warm.  The drinking water in my 5-gallon casks outside was slushy
the next morning.  Even TWO electric heaters wouldn't have been able to "cut
it" in this case.  There isn't much 'R' value to canvas and vinyl.

Boondocking (camping without any hookups) is the last, big "pioneering"
challenge for me:  It is satisfying to do all the work and planning necessary
to keep my family warm and fed for several days without the luxury of an
electric hookup or water nearby.  Camping like this is generally more secluded
than where there is electric hookups.

That's one too many.

I'd like to see the NPS BAN hookups on ALL their sites except for hosts and
staff.  This keeps the wimps and their noisy technology in the PRIVATE
campgrounds that are outside the nearest town.

This would help the private campground industry and improve the ambience of
wilderness campgrounds.  (Gensets between 2-3pm only?)

I can dream...

Another example of how everyone is different.  Angela and I think WE are
spoiled by being able to NOT camp in campgrounds, but instead having the
luxury of camping in a clearing deep in the woods away from
everyone/everything.

Many folks CAN'T "dry" camp because their RV isn't properly equipped and
provisioned to do so.  Many fear the unknown.  However, anyone that has tent
camped can certainly remember what it was like BEFORE they used an extension
cord EACH time they camped.  If the power goes out in an RV, you are pretty
much back to primitive tent-like camping.  No big deal.

For me, it's a challenge to ensure that we have all the comforts of home a
long way from an electrical hookup.  It takes some extra work, but the
benefits are huge.

A friend spent his visit to Yellowstone National Park...

<http://www.nps.gov/yell/>

...safely and securely PLUGGED-IN at a private campground "just outside" the
park because there are no hookups IN the park.  (One exception)

Many folks, particularly those from east of the Mississippi River, that have
NOT visited our first national park, tend to forget that the park is LARGER
than several eastern states.

Camping "just outside" the park is a 50-mile commute!   :)

Not for me!  When WE visited there, we spent five nights, toasty warm, at
Norris Geyser Basin campground - living in the wilderness and soothing quiet.

Look, ma!  No hookups!   :)

Camping there during "high season" wouldn't have been to my liking.  That is,
if we were to have gone in July or August, we wouldn't have needed artificial
heat to stay warm overnight but we would have had to endure traffic jams and
THRONGS of people.  That's not my cup of tea.

Instead, we went right after school got out - the last week in May.  Of
course, it gets downright COLD up there that early in the season.  I'll never
forget the late afternoon we got back from day-tripping and Leslie made a
full-blown, x-course meal of fried chicken, mashed potatoes and gravy.  We
hung wet laundry from a line strung between the two bunkend poles.  We then
crawled into bed.  The 12VDC furnace cycled all night keeping us cozy and
dried the clean laundry!

In the morning, with a hot cup of coffee, I stepped-out into pure wilderness.  
Once just can't do that at a KOA.

Whether one is absolutely secluded or "just" camping in a wilderness with a
handful of other campers doesn't matter much to me.  Camped in a private
campground, with full hookups, with a neighbor close enough to hear their
conversation is OK - for what it is:  A place to hookup, do some laundry, go
into town to restock BEFORE you head into the wilderness!
