The first three words of this answer are correct.   After that,
remember this is the same fellow who thinks trailer length is a
crucial factor.

We used ac/dc tv's (on 12v) in our rv's for years.

That may be your idea, but some of us are on the road a while and like all
the conveniences! <g>

Whoever came up with that idea should get on their meds real quick
before they do themselves damage!! <giggle>

The whole camping idea has to do with drinking lots of beer while
watching TV; and eating the kind of stuff that will impel your doctor
to suggest that you consider going on statins 'cause your cholesterol
levels are sooo outta whack!! :-)

Waaay back in the '70s when we got our first TT; in looking over our
"camping" checklist, our kidz got such a kick outta seeing stuff like
"TV, TV Guide" on the list, that not only did they keel over with
laughter, but couldn't resist showing the list to everyone in the
neighbourhood! <har!>

But the TV was an essential part of our RVing equipment. It was a
Zenith 12 volt 12" BW unit, that not only provided our morning news
and evening entertainment; but also served as a battery monitor. When
the 12" picture got down to about 8", we figured that it was probably
time to either recharge the battery, or simply stop watching TV. :-)
Other than the lights (and even with that, we had an optional propane
wall-mounted mantle lamp), nothing else in the rig: fridge, furnace,
needed any kind of 12 volt input.

As for the kidz . . . !!  Perhaps only something I should confess to a
priest; but as a parent, I have to admit that I've been a total
failure. :-(  Although I've made every effort to teach them the art of
decadence; now in midlife, making more $$$ than they will ever know
what to with; for whatever perverted reason, they still seem to
perceive some sort of merit in donning a 45 lb packpack and heading
into the wilderness in mid-winter with temps ranging down to the -20F
range!!

As a Dad who tried to do the right thing (well, at least sometimes), I
fail to understand why my kidz continue to derive so much pleasure
from enduring so much pain!!

What can possibly be better in life than TV, beer, and pizza!?!?

I don't want to go for a walk during every minute of the time
that I am awake. When the sun goes down, I like to go in
and put a DVD in and watch a movie on my 32 inch LCD HDTV.

Thank you for your thought provoking response.  I really didn't buy a
trailer to be a camper and sit around the camp fire on vacation.  I bought
one because I am dying of cancer and I want to see some places before I die.
It is too difficult with all my side effects and the number of times I must
be in a bathroom with lots of medical stuff.

I don't necessarily have to have all my toys and comforts with me but
watching the news and keeping up with NASCAR are things that I like to do.
I suspect I would have more of a chance to enjoy swimming pools and saunas
if I stayed in Motels but that just isn't working out very well.

I don't think my priorities are so far out of line.  I think that your
priorities may need to be adjusted because if you are going to spend all of
your time looking for people to send grouchy messages to you are not making
yourself a happy person.

I'll try not to turn the TV on when you are near my camp spot.  Take care,
Harry.
