Do what is right for you!
Sometimes I use a drop in lil' baggie and sometimes not. If it is just my immediate family, chances are we don't use one. If we have company, which is usually most of the time, then if it needs a drop in a day later, then so be it. Sometimes, I forget and nothing is used. If it needs it, use it. If you can hang with the smell of full blank tanks, it is no one else's business!
For me, after dumping, I drop a bit of Pine Sol with gallons of water in the tanks and then drive to storage. I try to keep water in the bottom of the tanks at all times. I like the hint of Pine that leaks out from all the splashing during the drive. It also cleans the walls if anything is stuck. Nothing should be stuck since I have tornado tank cleaners installed on each tank. When I dump, I am that guy that sits there for several minutes and let the tornado cleaners do their job. I have 4 tanks so I do take a while. I try to dump really early in the AM or later in the PM to avoid the long lines.
Back to the original question. Do what is right for you!
Out here in CA. The motocross world of RV's are still very strong using the Toyhauler 5th wheel method. You don't see too many high dollar Class A's out in the desert; however, there are a few scattered around. Class C's are the middle of the road since most rental companies out this way hold a giant fleet of Class C's as the preferred vehicle.
I love my Class C and so does the family. We sleep 10 comfortable, 4 adults, 4 teens and 2 lil' ones. We usually camp with another family when we ride. There are no hotels out in the desert and so we try to fit as many people in at night. We also have 150 gallons fresh water and dual black and dual grey tanks for a total of 4 waste tanks. Using the military shower method, we can go a full 3 nights/days with everyone showering nightly, normal load of dishes daily, and the rig that handles 90% of the cooking. If we take long, hot showers, I usually have to dump and refill after the 2nd day to make it through the last night/day.
Not too shabby for a Class C.

2008 Gulfstream Supernova 6400N.
Rented for 4 years before making the plunge into ownership. Rented mostly class C's but had my fair share of class A's. Decided on going as big as my budget let me because it is never just us camping. Bought the rig new in '08 and still going strong.
Here is the link to a previous post about it.
Welcome! Now get on out there and camp!
