i think trailers look cooler than vans, something about them
My wife used to say the same thing with the trailer hooked up to my Suzuki Van. I kept the poles, step ladders and hose reel inside the van and my long ladders on a roof rack.
But the trailer wasn't man enough for carrying the tanks and went through several sets of bearings. Within a couple of years the trailer was rusting and the paint peeling off.
In those days I processed water overnight directly into my trailer, so if I ran out of water that was the end of the day. I used to carry 100 litres in the van mainly as balast to keep the van and trailer combination road legal, which I also used to use to top up the tanks in the afternoon. We didn't have a pump controller and drenched the windows with 3mm jets in our brushes, so water was always an issue.
Although it got me into WFP, in hindsight, I would have been better getting a van mount at the beginning. However, I can also understand how windies feel taking this step in WFP and want to take tentative steps rather than a 'big leap.'
My advise to anyone thinking of the trailer route would be to have the right size vehicle to pull it, and in the aspect of safety, I would go for a braked trailer. Sooner or later you will get stuck in a cul de sac on a hill and need to uncouple it from the tow vehicle - trust me on that one, I have a couple of those tee shirts. Reversing a small trailer with a car is more difficult than reversing a caravan on the same vehicle - again, trust me on this as well.
