This is our 3rd Golden, but at 4 months occasionally chews things he shouldn't, including the cats. LOL
I just may opt for a large, rather than x-large soft crate, for the next few months. He is crated at night for house breaking reasons and is learning to come get us when he needs to go out. The RV will be a new experience for him and I have seen others break training when not in their own home. I think we will just use a soft crate in the truck and in the RV for unsupervised time.
Thanks for the input.
