I've passed by that area, I believe, on the way to the Imperial Dam LTVA camping area.
I suggest getting a waste tote that can handle most, if not all of the liquid from either the gray or black tank. I have 32 gallon gray/black tanks and have a 30 gallon tote. Think about how you will refill your fresh water tanks on the trailer. Some use expandable bladders that could fill your tank in one trip. I use four 6 gallon water jugs, and make a few trips when it's time to top off the tanks.
If you're using your batteries much at all, get at least a 2000kw generator, and if you need to use your air conditioner, you'll need a larger unit than that. I typically run my generator 4 hours more or less a day for just using lights, television (using a small 800 watt inverter), and charging computer/phones. If you don't get your batteries close to a full charge daily, their life will be drastically reduced.
Instead of investing in a generator, consider going with solar panels. You'll get plenty of sun down there to handle most anything, except air conditioning-unless you get lots of panels and many batteries. Lots of solar related threads here that would help you figure out what you need in that department.
Learn to strictly conserve your water, both the use of fresh and the way you manage your waste water. Doing that will help cut back on the number of trips you take both refilling fresh and dumping waste. I've boondocked the Quartzsite LTVA a few seasons, plus spent a little time at Imperial Dam.
