30 amp hookups, sewer hose

Hi all

Fairly new to RV'ing, so far this has not been an issue but we are planning some more extensive trips so...the motorhome came with a 30 amp male plug and a 20 amp typical household three prong adapter. It also came with a 6' gray water/sewer dump hose. This has been fine for the few parks we have so far but should I be thinking about getting some 110 V adapters and a longer dump hose? Thanks in advance.

  • I can telll you 40' sewer hose(with connections) is the most you can fit in most all square tube bumpers and still get the end caps on . Also carry additional 35' power cord extension ( mines 50 amp) last year I used it all . Had wheel ramps up to 7 1/2" of lift,only needed 3" lift the rest won't be comming any more.
  • You definitely need more sewer hose. I carry 50' total of it, and was really glad the one time I had to use all of it, stretched as far as it could stretch. You just never know what the dump station is going to be like.
  • Along with the adapters you already have I would also add One Of These they are handy to have at a campground that has both 50 amp and 30 amp connections,I have found that the 50 amp connections are in better shape.

    As for the sewer hose I would get A Rhino Flex Hose along with This that I have yet to use and This Connector so you can see that your tank is empty of all debris.

    yup. we carry about 50' of sewer hose (it compresses down to a lot less length) and 50' of water hose. ya never know.

    as for electrical...our two previous MH's were 30-amps and we carried a 30==>50 adapter and a 30==>20 adapter. now that we're a 50-amp coach we also carry a 50==>30 adapter. in one park I had to hookup to a 20-amp conection which meant 50==>30==>20 amps.

    I try to follow the Boy Scout motto...be prepared.
  • I carry 40' of sewer hose, 20ftr and 2 10's along with the connectors to put them together. I also have a 25ft 30 amp extension along with a 50-30amp adapter. I have a 25ft fresh water hose and a 50ft fresh water hose. And if they have cable, 50ft of that. Not to mention a 25ft 20amp extension cord and a 30-20amp connector.

    And yes I've used all of that at some point or another, never needed all 3 at the same time. Glad I have them for the once a year I may need them.

  • Get the adapter. They are inexpensive. Six feet of sewer hose is a minimum of 14 feet short of what you need.
  • My rule of thumb is, measure the distance from the dump valve on your camper to the farthest end of your camper. Add add another 10 feet, and that is the minimum amount of sewer hose you should have. The first time you pull into a camp site and the sewer connection is at the rear of the camp site and not on the side of the parking pad, you'll be glad you have that much hose.

    Or do like me, and carry about 60 feet of sewer hose combined, in all different lengths to suit any occasion ... you just never know.

    About the 110 adapter? They are OK to use in a pinch, usually, they are plugged into a 15 or 20 amp service, and will not be able to provide the full 30 amps to your camper. This is no problem, except you won't be able to run everything at the same time. Once you reach the capacity of the breaker in the breaker box, the breaker will pop. Turn something off. Usually, about the only thing that can run is the air conditioner and nothing else. Or leave the air conditioner off and run a television and a fan. Remember, your power converter built in your camper also pulls electric power. All those little devices plugged in will use up amps also. Once all those items reach the breaker capacity, "Pop goes the breaker!"

    That's why so many, me included, go through the cost and trouble to install a normal, regular 30 or 50 amp RV receptacle at home. In a campground, always plug into the 30 amp service.
  • Dump hoses...I would either do a 20' or 2-10' sewer hoses. Don't forget some connectors to put together.

    Not sure about your 110 volt adapter question. I have 30 amp in my rig which plugs directly into the 30amp outlet in the electrical box. I do use a surge protector and I carry a 30 to 50 amp adapter just in case there are no 30 amp sites available.

    Also, I carry 2-25' water hoses and 1-10' water hose.

    Safe travels
  • I carry extra adapters, extra sewer hose (total of 30') and extra water hose. I have used them all at one time or another.
    Some rv parks carry supplies.
    Many, don't.
    Be prepared.
