Yeah them 19's ain't great, the older dash 1 zaxis were a bit better tho, I'm not sure the 25 will much more productive than your Hyundai. I only take the 3 tonner when absolutely necessary, I'd rather work the 1.5 flat out than it feel tight with the 3. And the other thing is a 3 tonner is bloody heavy towing round, don't care what anyone says you have to always have your wits about where as the 1.5 is pleasant to tow. The last thing is rates, I get £25 a day more for the 3 ton, it hardly warrants the difference in purchase price or running cost.
Just my opinion mate, but I've been asked by two customers this week why I turned up with the 1.5 when the 3 would fit, it's simple, it's easier for me and cheaper for them.
