Triple axle everytime for me, spreads out the weight better and pulls easier in my opinion. I also prefer the extra carrying capacity provided by the triple axle vs tandem axle. Someones worried about the cost of 2 more tires....really... your spending 75-80K on an RV so don't be worried about the cost of two more tires!! If that's all that was concerning me with purchasing an RV as to whether I would have to purchase 4 or 6 tires down the road, then I think I would hang up my keys and stay in a bricks and sticks house, but that's just my opinion. Get the triple axle and have fun camping and spending that extra $500 in 5 years, you won't regret it!!

I'll have to admit if the cost of two more tires was the only expense then I'd have to agree.

But I, for one, would love to have disk brakes but those are substantially more with a triple axle, and suspension improvements are also around 50 percent more. I installed the EZ Flex components and wet bolts which costs more for the triple axle. If you have your wheel bearings done rather than doing it yourself, higher cost for a triple axle. If you do it yourself, you looking at more time and work with a triple axle. Want to add a TPMS? Higher cost for a triple axle. And higher tolls if you happen to hit a toll road. And the friction of 6 tires rather than 4 means a hit to your mpg. Not a big deal unless you put several thousand miles a year on it.

So there really is more than just the cost of an extra set of tires involved.

In theory it would seem all those additional components would provide for a better towing experience. Those that tow regularly for long distances would stand to benefit more from the improvements not less.
I would also think six tires carrying less weigh per tire would last longer than 4 tires carrying more weight per tire.
