Some basics that we found worth while:
- Adjustable spring loaded cupboard rods (holds things from sliding out of the cabinets when traveling, works well in refrigerators too)
-Oxygenics shower head if you have a shower in your TT. Saves water, feels like more pressure, longer shower.
- Lynx Stay-Put hangers for any clothes you're planning to hang in the closet.
- Lynx Levelers (the orange pads that are stackable. we have 2 sets and use them each time we go)
-ADCO covers for the AC unit and tires. Keeps the AC from gathering leaves and branches during the storage season and the tire covers protect your tire investment during the summer while it's parked in storage.
- Unique "Digest It" for the black tank. Benefits camp park septic tanks too...
- Water hose: big difference between the standard home hose vs an RV water hose, be sure to google this before buying one. If you plan on drinking water from your water storage box, a good filtration system or additive might be in order. We generally don't drink from the tank and carry filtered water from the home. Note: too restrictive of a whole system water filter will cause low water pressure in your shower and lines...there is quite a bit of info about this in the forum too. But, we do have a 45 degree water connection that we connect our hose to so that it doesn't kink or cause needless pressure at the water inlet on the rig.
- Depending on your length of stay, 2 - 6 volt batteries might be better than 1 or 2 12 volt's. Search the forum for more info on this as well.
- An accurate tire pressure gauge is always handy...don't want to pop any tires during your trip due to under inflation. I think TPMS is standard on trailers these days, but i'm not positive of that.
- We use the EZ flush brand of RV sewer hose with the 18mil spec. This is a pretty thick hose compared to the flimsy one that was supplied in our camper hatch. I bought this at a campground after finding out just how flimsy the original brown one was that came with the camper. I fully agree with ghrodes50 about the "doughnut"...definite must have. If you want to store the sewer hose and accessories outside of any of your storage areas...search the forum for people that have purchased a 5" or 6" vinyl fence corner post and have mounted that under the frame for carrying such items. Best thing I ever did...I didn't like the idea of having that hose and all it's parts carried in the same hatch as my water hoses and other supplies. (example - http://www.forestriverforums.com/for...ose-10526.html
) But maybe you're one of the lucky ones and have that already built in to your rear bumper.
Oh...one more thing...I bought a 45 degree clear connector that goes between my drain valve and my hose connector...that way I can see when the black tank is absolutely clean when I'm winterizing or getting ready to store it. Last thing I want is any "left overs" sitting in the tank all winter long.
Don't forget the disposable sanitary gloves and hand wipes for cleaning up after the fact. Just good hygiene goes a long way in my book.
These are just a few things that we've found helpful during our trips and that I have first hand experience with for the last 4 years or more. I hope that helps get you started.
