'I suspect that you've come up with an inflated price by adding a bunch
of 'standard' stuff as if it were 'optional'. Don't be disappointed if
buyers make offers much below your asking price.
Example? I've never heard of a class B (except SMB) where the furnace is
optional. It's part of the base package, and should not be added in
figuring either the new or used price. Same goes for many of the items
on your list.
Dunno how you'd find out what was truly optional, tho', unless you've
got the original sale paperwork.'

REPLY: It says right on the NADA site for my Brand what is considered
standard and should not be added in.. And that was : Water Heater, Roof
A/C,  and Stove. So, i added in everything else but those. If this is
incorrect to do, then, I think NADA needs to be more accurate.

'DIY 'upgrades' will return little of their cost, unless they're
universally desirable, and the workmanship is impeccable.'

REPLY:  An Aux. Trans . Cooler and Aux. Electric Radiator Fan offer
definite advantages especially when towing or loading up the RV to the
max.   All the upgrades I made were done tastefully and with good
workmanship.

'"Science has discovered the missing link between apes and intelligent
life. It's human beings."'

REPLY:  There are no 'missing links'  in the macro-evolutionary chain
because the entire Chain is missing !  ;   before you can have macro
evolution taking place, you have to have life coming from dead chemicals
. which real science says is  utterly impossible due to the 2nd Law of
Thermodynamics and the Law of Biogenesis which has never been
controverted. Life can only come from life itself , and even atheist Dr.
Francis Crick who is the cofounder of the DNA structure said that DNA
could NOT have arose spontaneously out of the envirnoment.  In fact,
one day ... the entire myth of Human Beings coming from Hydrogen gas
left over from the 'big bang' in addition to macro evolution...will be
regarded as the biggest hoax in all of human history for the sole
purpose of denying the obvious personal Theistic Creator/Designer which
is due to ones personal ulterior motives (that almost always involves
some degree of immoral lifestyle choices with the biggest one being :
sexual freedom).  Heres what some popular Evolutionists are saying about
their own Field of Study :
___________________________
" It is therefore a MATTER OF FAITH on the part of the biologist that
biogenesis (evolution) did occur and he can choose whatever method of
biogenesis happens to suit him personally ; the evidence for what did
happen is not available" --- Evolutionist Prof. G.A. Kerkut of the
University of Southampton. Source : Implications of Evolution. London.
Pergamon Press, 1960, page 150.

This Evolutionist  is a strong supporter of Evolution theory :
" The more one studies paleontology, the more certain one becomes that
evolution is based on FAITH ALONE" -- Evolutionist Prof. T.L. Moor .
Origins ? The Banner of Truth Trust, 1988 page 22.

Another confession from an evolutionist -
" We Palenontologists have said that the history of life supports (the
story of gradual adaptive change) , all the while really knowing that it
does not" -- Dr. Niles Eldredge. Darwin on Trial. Regnery Gateway, 1991,
page 59.

This person comes clean finally. A confession of extraordinary honesty

" The record of reckless speculation of human origins is so astonishing
that it is legitimate to ask whether much science is yet to be found in
this field at all" -- Evolutionist Dr. Solly Zuckerman. Darwin on Trial.
1991. page 82.

From an article in Science Digest Special---
" Scientists who utterly reject Evolution may be one of our fastest
growing controversial minorities ... Many of the scientists supporting
this posiiton hold impressive credentials in science" . -- Educators
Against Darwin. winter 1979, page 94

A huge number of Scientists know Darwinian Evolution is an utter fraud

" I believe that one day the Darwinnian myth will be ranked the greatest
deciet in the history of science "--- Prof. Soren Lovtrup, Embriologist.
Darwinism : The Refutation of a Myth. 1987. page 422.

" The more i examine the Universe and the details of its architecture,
the more evidence i find that the Universe in some sense must have known
we were coming"--- Prof. Freeman Dyson, Physicist from Princeton Univ.
'Disturbing the Universe' . 1979. page 250.

Here is a much revered scientist :
" The more man is imbued with the ordered regularity of all events, the
firmer becomes his conviction that there is no room left by the side of
this ordered regularity for causes of a different nature than a Creator"
-- Albert Einstein. His LIfe and Times. page 286.

And finally, the bottom line from an "agnostic" Astronomer :
" For the scientist who has lived by his faith in the power of reason,
the story ends like a bad dream. He has scaled the mountains of
ignorance, he is about to conquer the highest peak and as he pulls
himself over the final rock, he is greeted by a band of Theologians who
have been sitting there for centuries reading Genesis 1:1 : In the
Beginning God created the Heavens and the Earth" --- Prof. Robert
Jastrow founder of Nasa's Goddard Institute. His book, 'God and the
Astronomers. page 116.

To keep on having 'faith' in the impossible of ever having occured by
natural causes because you dont want a personal Creator to exist.. is
the epitomie of being disengenuous to oneself. Its not a matter of
needing evidence to believe (because people already DO) ; rather, its a
matter of excersising ones WILL to embrace the Creator whos been trying
to get your attention over the many years of your life. Rejection of the
Creator now, results in your earthly choice being granted for all of
eternity .... which will never ever end. Please dont make that
unfortunate decision due to pride and personal rebellion of God.
