Yeah, they said the tires are approaching their age limit and will need to get replaced in the next year or two.
Since they're getting out of RVing, they're leaving us with all of the accessories they have in the RV, so we can take an inventory of what they have and what of it we like/is usable etc.
This RV has been sitting for a year or so. It does start and run fine (engine and generator) and was winterized before sitting. So we have to figure out getting a lot of this un-winterized, water etc. I'm not certain of the fresh water tank size, but I'm assuming that some chlorine/bleach tabs would be a good idea to help keep any mold/bacterial growth under control. Really we figure the water we'll use for the washer, shower, etc. etc. but not for drinking.
It's great that it comes with all the "little stuff" to get your started.
a pro-tip. Put a pad of paper somewhere easy and as you are on your first couple of trips, note the thing you wish you had "light lawnchair for a guest" "folding picnic table for when the site doesn't have one". then you can add those things post trip (or even during the trip).
Most people do a quick weekend or two as shakedown trips. someplace an hour from home so it's not a big deal to bail if something is screwed up, something near a store, so it's easy to grab some of those things that you figure out you want, but don't have.
On tires, I know i'm speaking to the choir, but REPLACE THEM BEFORE THEY'RE DUE. You don't want a rotted tire to blow, causing danger, damage to your coach, and a big pain in the butt on your fun trip. They'll always age out before they wear out on an RV.
Another pro tip. After 1-2 trips, dig through the cabinets/lockers and remove all the stuff you NEVER USED. You'll surely have different styles than the previous owners and they probably carry a lot of stuff you'll never use.
Make sure you carry a few spares. fuses, bulbs in addition to actual consumables (trash bags, paper towels, RV toilet paper, hand soap, dish soap, OFF, etc)
You'll find that a few things are not intuitive, perhaps the awning. figure these things out in advance of the trip can be an easy, low stress way. maybe do a campout the first night you get it home in the driveway, the kids would love it!
dump the black first, then the gray to wash out the worst of hte black stuff from the pipes/hoses. don't leave your dump valve open even on hookups, or you'll get stuff to pile up in the black tank.
get disposable gloves for dump duty and keep them in that compartment
make sure you have a few sets of keys for evyerhthing so both mom and dad have one, plus a hidden one somewhere.
watch for leaks, particularly in roofs and roof penetrations. these can ruin an rv over a winter if left undetected. a lot of folks do a scheduled roof reseal every so many years to avoid the risk.
this gets into preference, but here goes: we love having a little propane coleman stove to cook outside with, and do 75% of our cooking at the picnic table despite having a 4 burner stove in the rv itself. this keeps heat and smells out of the rv and is fun.
much like airplanes, teach the kids that tiny plastic latches are fragile, and dad would rather spend time doing fun things with them rather than fixing them all the time, so please be gentle with doors and drawers.
