hi scotty'
if you search IN the tow vehicle section there are some threads related to 4-rnr towing....
-traveling light...
i don't think that many folks
intentionally travel heavy.
but it is a house on wheels, so not carrying water, food, clothing, toys, entertainment (books, movies, beer!)
is sort of counter to having the space and appliances.
then consider BASIC tools, lp gas, the hitch apparatus, options and so on...
the 25s all weigh 5k+ and max out around 7,000 lbs with gear and fluids.
NONE of the a/s website weights include options or lpgas...
the tongue weight listed for 25s again are just estimates and range from 720-850 again this does NOT include 40-60 lbs of lp gas.
almost always the limiting issue for 'dry camping' becomes adequate WATER for the most basic needs...
-toyota suv payload...
the maker suggests the payload max for the 03 runners is 1000-1100 lbs.
the trailer tongue WILL weight 800 or 900 lbs...
add a hitch (100 lbs) and there is NO ROOM for people or gear or much fuel IN the runner...
without being way OVER payload.
and you won't be able to supplement fluid needs by carrying water (or beer), or extra lpgas in the runner either...
so payload IS a big weakness in the 03-05 runners...
-towing capacity...
while the t.c. for 03 runners is 5-6k, that is best case rating, as in NOTHING in the suv.
every pound of stuff IN the runner subtracts from towing capacity....
FIND the GCWR for the runner, that's the grand total limit of all mass moving...
but don't exceed the payload without some serious thought...
many of us try to limit mass to 80-85% of these max parameters for added safety and mechanical wear...
-energy needs....
while the c pap can be adapted to
12v, it will still use significant energy (amps) which will deplete 2 typical rv batteries...
just look up the amps required for the c pap and the amp hours available in the battery bank, this is pretty simple to do...
100 watts of solar will NOT be able to keep up with basic electrical needs so dry camping will be limited to 2-3 days...
and IF the furnace is running perhaps only 1 nite, with the additional energy load needed for breathing!
so to do this with solar MORE BATTERIES (storage) will be needed,
which means MORE WEIGHT in the trailer and on the tongue...
so again the
runner payload limits become an issue...
while a small genset (30-50lbs) can be used to restore the battery capacity OR run the c pap on 110/ac juice when needed.
if c pap is really needed or important, adequate power is a must.
consider have 2 sources of energy by carrying a genset AND having solar with an adequate battery bank...
it is ALL doable, but you may need a bigger t.v. AND need to give more thought to equipping the trailer...
lots of good solar stuff has been posted, so to for gen set info and t.v. wisdom!
have a great time sorting it all out...
cheers
