You will have to join in order to see it, but it's a free website.
Rockwood only changed the manual every 8 years or so, so don't be surprised that it's listed for 5 years before yours

Amazon or RV Supply.

check for a plate riveted to the "A" frame (towing frame) top or side of frame
find and ask a distributor where it is found

i am not sure but it maybe side of the engine give these websites a try www.alldatadiy.com and www.autozone.com if all fails stop by your local library and get your hand on a Haynes auto repair manual for your camper or a 1983-460-engine wish you the best of luck Michigan Man.

There is generally a water pump fitted. In the early days of campers the water had to be pumped manually by either a foot or a hand pump and later people grew lazy and so electric pumps were fitted. At first these were controlled by a switch or button close by each faucet and needed to be held pushed in for water to flow - for obvious reasons the flow stopped when the button was released.

Later people grew impatient as well as lazy and also tended to be slightly wealthier and liked to take a shower so the system was automated. The electric pump was integrated with a water pressure switch so when a faucet is turned on the water pressure fell and turned on the pump and when the faucet was turned off a significant pressure would build in the pipework, sufficient to cause the pressure switch to turn off the pump.

The scope of the equipment varies a great deal depending on the amount of water carried, the size of the camper, the hot water system and the price range and could be anything from a single submerged pump to a multipump system to provide a luxury shower.

I suggest you obtain a manual or owner's handbook in order to discover the equipment fitted to your camper and how to operate/troubleshoot it. Such information is of particular importance if the camper will encounter freezing temperatures during the winter lay over. Failure to winterise properly can cause a great deal of expensive damage.

The cable pulleys will be behind something in each corner of the camper , you will need to remove the wall somehow at the bottom corner , sometimes depending on the model it is easier to remove the outside panel and put the cable back on the pulley then put the outside panel back on , be prepared to damage it though as they can be very stubborn to remove but you can repair it later .
