Stacy the hauler in mind is a Supercross 18'er pretty much minimum necesities.. 2 burner stove (how often do you use the stove when you have a pizza cooker anyhow), smaller fridge, heat air, dual gaucho's, drop down bunk, fiberglass sides and the other usual toyhauler amenities..
Honestly if i thought i could pull a 25'er SAFELY i would be all over it. Im playing the 75% of max towing capacity rule. I want to stay @ or below 75% of what Nissan says the armada is capable of which is 9k lbs. Some places list dry weight for this one under 4k but realistically your looking at 5k empty... by the time you get water and toys loaded up your looking at 7k worth of stuff.. which puts me right in the 75% range. or just a hair over. somewhere just shy of 7000lbs im figuring. Which is below my tow rating on my armada. With the taller gears tranny cooler and Anti-Sway i should be just fine with a 18' hauler. Which is just the right size for me and the wife and 1 bike maybe 2 down the road.
