as for manuals got to each items website like dometic, and download the care and feeding ones, FR site has a few but pretty vague.
common sense will go a long way
outside it needs to be washed and waxed like a car, i wax mine once a year and the front cap about every trip
the whole thing top to bttom gets washed with a good quality car soap about once a month
no harse chemicasl in the toilet, it dries out the rubber seals
little mineral oil or castrol oil once a month in the toilet bowl and sink drains will help keep the vavles lubbbed up
if you sotre in in winter, DRAIN all the lines and then put in some RV anitfreeze during layup
this includes draining anf bypassing the water heater, I put some in the water heater anyway if she is empty during cold times,
i know we have a good list somewher, i just cant find it now
but ask away , lots of good folks her to get you through it
oh if your site has trees overhanging the rig
you need to trim the dead or looses one away, they will puncture the rubber roof very easy, plus let ants and other critters have a direct free fall entry to vent
