Congratulations Dave!
Look in the compartment on the back of the trailer for the drain lines. There should be small pipes that come out back there. They will have valves on them. There should be at least two valves. Do you have a screw off cap on the front of the trailer? If so, that is the water fill location. Be careful and check your water tank to be sure it is not cracked, has holes etc....before you fill it up. The water pump should be up towards the front on the street side of the trailer below the dinette, if you have the front dining room.
Please post pictures so we can see what you have.
Enjoy your new trailer!!
