First of all, here is a thread that I started about 17 months ago:
http://www.fiberglassrv.com/forums/f...ces-41624.html It really took on a life of its own, and addressed many of the issues in this thread. Joy A. contributed heavily to this thread and I used pretty much all of her suggestions.
I bought all my RV water stuff from Wall Mart and Camping World.
I have a 25 Ft , a 20 ft and two 10 ft fresh water hose. Per Joy A.'s suggestion I have quick connects on all the hoses. That makes it very easy to put 2 or more together if I need extra length. I have only been at one camp site where the 25 foot hose stretched all the way, but I didn't anything longer. Most of the time the 10 or 20 ft hoses work just fine. I suppose it is possible to need more than 50 ft, but I can't imagine that happening all that much!
I also have a water pressure regulator, an elbow and water spliter. All metal and designed for RV use, and bought at either WalMart or Campers World. The white RV hoses are particularly economical at WalMart. As are the quick connects.
I once used a plastic spliter provided by a camp ground I stayed at, but found it wanting. So, I always use my own stuff.
I also carry a water filter which I found invaluable a number of times. For instance, I recently hooked up at a friends house, and she recommended that I use my filter as the well water was sandy.
I really didn't pay all that much for these items and they store easily in my trailer. The quick connects do add up, but they are well worth the price as I can put hoses and plumbing hardware together easily and nothing
leaks. Once hooked up, I don't have to worry about problems with water pressure, leaking, etc. I can just enjoy myself till time to take down camp.
I also invested about $6 in a leak prof bag for the hoses. That way I can store my wet hoses between camp grounds. When I get home I sanitize and dry air the hoses and hardware used on the road.
One more thing, I recently bought a 25' coiled hose for my black water tank. Many times I found myself at dumping stations that did not provide a hose. This hose takes up virtually no space and is stored with my black water equipment.
