First big trip - Newbie questions

How important is it (for you) to flush the toilet or use the sink while you're on the road? If important, place just enough water in the FW tank to flush the toilet (or use the sink) a time or two. If not, you may want to leave it empty to save weight (if you're concerned about weight). As for the black-tank deodorant, you might consider following any directions noted on the deodorant container. We always place enough water in the black tank to "cover" any eventualities---regardless whether we use deodorant or not.

Enjoy your first, big trip with your Palomino!

We always add some water to the fresh tank. Might want to wash some dishes or might boon dock somewhere and don't want to be without. We don't usually fill it full unless we know we will be boondocking for most of our evenings. I don't have a black tank in the TC (cassette toilet) but in my old RV we always put a few inches of water in the tank. You want to make sure #2 stays wet for later draining. Makes it much easier to dump.

We always fill the freshwater tank full before we leave. depends how much you're under you're weight cap. We usually put the deodorant in when we first use the toilet on the trip.
