You got it backwards. Condensation is pretty much a myth with plastic tanks, but is a concern with a metallic slip tank. Besides, just run em down low and fill when running the truck again.
I've never subscribed to the full tank for storage theory and I shelf many engines every year off season. Fresh fuel (especially if talking gas, not so much for diesel) trumps the potential of moisture IMO, in most cases.

I had an RDS 30 gallon aux tank installed on my F250 earlier this year. I love the flexibility the extra fuel gives me in planning my fuel stops. One thing I discovered about my truck however is the fact that it seems to have a vent on the top of the internal tank. I discovered that the hard way when I left the manual valve open. What a mess. I installed a solenoid valve in the fill line and wired it to one of the upfitter switches in the cab. Now when the gauge gets down around 3/4 of a tank I'll turn the valve solenoid on and watch the level slowly rise while I'm driving without risk of overflowing the internal tank. If I forget to turn it off when I cut the engine no worry of overflow since the circuit is only hot when the ignition is in the on position.
For me the aux tank was the cheaper option even though I had the aux tank installed professionally.

Had the Titan installed in my 2016 F350 early this spring. Love it and glad I went that route instead of the in bed. Only one tank to fill. No thoughts, just fill. I have Almost tripled the towing range of the F350 with this as I typically refuel when I have 20-30 litres remaining. So now I have 170 litres of useable fuel before fill and before I had 70!

Best addition to my truck ever.

And the 5 gallon jerry can that was suggested earlier doesn’t even compare. You aren’t extending your range with that, just carrying some emergency fuel. Not the same thing.

I personally don’t care to extend my range. 250 miles or so we stop for fuel along with other reasons. Just carry the 5 as a backup.

Exactly, you and I were after two different things, I wanted extended range between fills, you wanted emergency fuel. Hope I didn’t offend, I just was pointing out the difference.

No offense taken!

I think everyone should try without an auxaliry tank to see if they really want one.

Peggy bought mine for Christmas and it was a couple years before I installed it. I finally did because the last trip I was off on the two lane roads a lot and got tired of trying to find fuel stations that I could get into and out of easily. A fair amount of wasted time finding a station and then discovering I couldn't get to the diesel pumps without a lot of jacking around. Immediately after installation the stress level dropped a bunch.

However now we only travel 250-350 miles in a day and could probably get by without the tank, but when we were doing 400-500 miles a day it was a godsend.

I have a 60 gallon RDS tank with to box, it gives me more than 12 hours of drive time with the trailer. So plenty of time to find a campground, go do our touring, then find up before fueling and hooking up and moving on. I consider it a convenience that I can choose when to stop on my terms and not when forced to by necessity.

I like my fuel range with the 50 gallon Titan tank for yet another reason. I live in PA where the fuel taxes are the highest in the nation, so for two years now, I have bought exactly one half tank of fuel within the state. My last camping trip is an example, I took two 5 gallon cans along and went the entire week without giving the greedy governor a dime. After returning home, I travel a bit farther to a station out of PA to fill up the truck and any empty gas or diesel cans. While out of state, I also buy groceries other items.
