I'm in desparate need of a quality dog gate to set up in the back. The ones bought at local pet stores are flimsy and fall over. Anyone know of a place or person that can make a quality one. The ceilings are soft so the pet store varieties can't get secure enough. If I can't find a good one or alternative I might have to sell 4Runner and get Tacome with a cab and I don't want to do that, I love my 4Runner! Thanks!!!
