Here's my two cents worth....
Don't tow with anything other than 3/4 ton.
I'm not sure if I should start a new thread here (?). Because the OP is asking about a 25, and I'm looking at it from a 22 perspective. But then you (mngrant) are talking about towing your 22 (which is why I'm responding) and too, perhaps some of what you write if you reply will apply to the thread.
I'm hoping to buy a C-dory. One of the first things I did was compare a 22 to a 25 in order to decide which one would be "right." Of course the 25 looks nice and luxurious, so at first I thought of course, a 25! But then I looked at towing weights. A big factor in favor of the 22, was that - at around 5,000# all-up, I figured I would not need a "top tier" tow vehicle.
Or to put it another way, if I need the same 3/4 ton truck to tow a 22 as I would a 25... well, that takes some of the perceived advantage from the 22 and might turn me more toward a non-trailerable trawler or sailboat (because although the 25 looks fabulous, that plus "big" 3/4 ton truck is just not the feel I'm looking for). Best to find out now, even though it may not be what I want to hear.
I have a Chev Duremax 3/4 which gets me up the ramps at minus twice and over the steep passes. I broke a self imposed rule of never tow with anything under 3/4. I tried to tow with a Tundra but the Tundra just did not do the job.
Can you tell more about this? A first-generation Tundra is (was?) at the top of my list as a potential 22 tow-vehicle candidate. I was actually thinking that would be the "ample" choice as compared to some others. In what way did it not do the job for you and your 22?
Research the issue and I am sure you will discover a 1500 series truck, any make, will not stand up to the rigors of towing safely as does a 3/4 series.
In my research I pretty quickly figured out that the 25 - at close to 9000# all-up - would be up in 3/4 or 1-ton tow vehicle range; but I was thinking that the 22 - at around 5000# - should allow me to ratchet that back a bit. Now it's sounding like that may not be the case?
I should mention that I figured that the types of vehicles that are *just* at the 5000# limit and/or have very short wheelbases probably would not be the best for regular long-distance towing (Honda Pilot, etc.), so I had ruled them out even though they had appeal. But I was thinking that a truck like the first-generation Tundra or similar, with a higher rating and longer wheelbase would work comfortably.
