Hey guys, after over 45 years of doing this...I got it right?? OH, I have had my share of BOO-
BOO's. BTW, you did not say if you dry camp alot. If you do, get a 3000W genset with sineway. Also look at a Weber "Q" BBQ. They are lite weight..work great and wont blow out in the wind. We had a Coleman??, RATS, just got a case of CRS. Maybe it was a "roadtrip". Anyway it was red, big, heavy and would blow out in any kind of wind. You might also consider get 2 small ceramic heaters, if you have hookups or a genset, and use those instead of propane. 2 batteries will help if you do dry camp...1 12V wont last the night when running the heater. Here's the deal, you probably dont have alot of outside storage but have a good amount inside. Keep all the heavy stuff in lower cabinets. Get some ponytail rubber bands to keep the upper cabinet doors closed. Put them oround the knobs on apposing doors. Try to keep the front of the trailer heavier than the rear. It has to do with hitch weight. A trailer loaded tooo heavy in the rear will sway badly when pulling at high speed (50 mph and over). Not trying to scare you...just the facts. You will need a WD hitch, dont care what brand, and learn how to use it. Make sure the TV and trailer are "level" when loaded. A little nose down, not alot, just a little, is OK. Next item, get clear plastic totes to use in your storage compartments (Wal-Mart again). That way you can see whats in them. Some on-board tool kits are a must, screw drivers, plyers, electrical tape, duct tape or even rescue tape, extra fuses. By all means get a good pressure regulator for your water hose. One set about 50psi. Buy cans goods and keep them in the trailer, but rotate them by the exporation dates. Get some kind of bag made of netting material to keep dirty clothes in. If you wash that load seperately, then all the stuff from the trailer will get put back in the trailer.
This is the last thing for now (fingers getting tired)......NEVER....EVER...USE your white water hose for flushing the black tank. Get dedicated water hose for that. Cause if you do do it, you first drink of water..could be your last.
Here is some sage advice about maintence. Before or after every trip, check all the "P"trap fittings and water lines you can get to, to see if they have come loose. All the wonderful roads we have. As to the water heater (HWH)......NEVER turn on the "red" switch until you are sure the tank is full. I always, after hooking up the shore water, open all the water taps, on the hot side, until they stop spitting air. Always leave some water in all the waste tanks (gray and black). Put Dawn liquid soap in the sinks and some kind of black tank additive. What to use is for a different time or read what people use. Always check your tires before every trip. Just walk around and check all the lites...in other words, just go around and "kick and sniff" everything.
BTW, what are you using for a TV (tow vehicle) ??
