Have had my Yeti 75 since 2008... 65 for 2.5 years, and got the 125 this year. Short of dragging it behind your truck for 5 hours, throwing it off a cliff, then putting it in the campfire, I don't see how you can hurt the things. The warranty thing is probably pretty moot.
Don't you have a walk around Proline? The 65 (or others) don't fit at the bow walkaround area? Yeti has extremely accurate dimensions on their website for each model.
If you don't need the cooler in the next 2 weeks, here is the link where I bought my last 2 Yeti's. You'll rarely find a Yeti cheaper than MSRP anywhere... this site saves you some $ and is legit. It just takes about 2 weeks to get the cooler. No Tax. Free Shipping!
