I agree. And even though I don't intend to take it on the Rubicon Trail,... dings & whatnot, still happen on tamer trails. For example, up here in the PNW, the trails tend to be narrow & can get very slippery, so it need take much, to slip into something you didn't plan too. (like a tree). Also, I wouldn't want to be worried about crossing shallow water, if I needed to.The skin of the TD would be some of a concern but you stated no hard core stuff. I just did a offroad trip 228 miles in the horizon and not one problem and that includes a 3ft deep water crossing.
I guess what I'm trying to say is - if you go off-road, even on easy trails, dings/rock rash/ abrasions seemed to just happen,.... And with the AT Teardrop - How do you fix a dinged corner (which wouldn't even have left a mark on either a Horizon or Chaser,... & if it did - it probably wouldn't cause structural damage). So, structural damage, & how to fix it, presents a bigger problem with the Teardrop, then it does with other trailers.
Problems is - As a single traveler, I really like the quick/easy setup, & the warm/dry enclosed sleeping area of the Teardrop,... much more than the Horizon option.
I guess here, like elsewhere - when there's options, there's also compromises.
Thanks again for your reply & info!
