We have a lab that we want to take with us when we use the TT. We do not have a twin cab truck so the only option is to crate him in the back of the truck. Do any of you have suggestions on what kind of crate to use and where to get them. I have been looking on the web but don't see any tie downs on any of the crates. Another issue is that he is elderly and will need steps or a ramp or something in order to get into the back of the truck. This question may get some folks terribly upset but could we let him ride in the TT while we're driving.
