Ive been looking into RTTs lately and I want to get one but I cant figure out what to do with my dog. He's 75lbs and I doubt he can climb a ladder. Does anyone else take their bigger dogs along for the trip in their RTT? I tried searching the forums, but I came up empty. Leaving him home is not an option, he loves the outdoors as much as I do. But lifting a 75lb dog in and out of a RTT doesn't sound like a lot of fun.
