- T5 SE 180
It's crude but works okay. We used to attach a longish flat web strap and then our mutt could roam around a bit outside while we kept the sliding door shut. (These days she's more inclined to stay in the van with us big dogs).That's a really good idea, going to try this before trying the D ring, thank you !
I find those stainless clips handy generally, you can get them cheap on Ebay or Amazon.
