Re: Innocent questions.... When you dump, make sure that both your black and gray tanks are over 1/2 full. If not, add water until they are. Then dump the black tank, and flush it until the water runs clear. Then dump the gray tank, which will clean any remaining sewage out of the system. Do this and there should be no need to rinse the hoses. Yes, it is best to store them in a container of some kind, best is a piece of PVC pipe with vent holes. If you have a hollow square bumper on the back, that is often used to store the hose. Or a plastic bin. Basicall, anything which it will fit into, keep drips from escaping and is vented to allow drying will work. I would not trust garbage bags to keep them in. The 50 to 30 adapter is good, so is a 15 to 30 adapter. DL, where'd you find that 30 to 20 adapter? I couldn't find one, so ended up making one. In water hoses, 25' is a good length. I also use 4' and 10' along with a handfull of brass 90 and 45 degree fittings. This 39' will handle most campgrounds, and I carry 50' of flat hose on a reel for non-standard stays. Make sure you get 'drinking water certified hose' because most hoses these days are made with harmful chemicals. Carry plenty of coax; the cable tv jacks are sometimes in strange locations. I started with 25' and that wasn't enough, then went to 2 x 25' and still ran into an insufficient cable situation. Now I carry 25' and 50' and so far that seems to be enough (plus the adapter to fasten them together) I've gone to a push on fitting for the cable source, since screwing the fitting onto those old, battered, dirty fittings can be annoying. Most laws restricting open beverage containers in vehicles specifically exempt the 'living' space of a motorhome. And as for letting them in? Not hardly. It is a home and no searches with warrents are allowed.
