Dog crate modification to our 2014 Interstate Extended: We are newbies to RV and bought the vehicle so we could travel with our two German Shepherds and and a little Yorkie/Dachshund mix. I removed the second row of seats, cut a Tractor Supply dense rubber stall mat, laid a piece of 3/8" plywood and another piece of stall mat directly under the foot print to raise it above the wiring panel bump out next to the driver side second row seat. I then built the base crate for the larger German Shepherd and angled the side facing the driver seat which added almost a foot of length to the crate. The stacked crate was angled to accommodate the curve of the cabin wall, maximize crate space, and preserve as much walk around space as possible. I secured the stacked crate with stainless steel plummer's pipe clamps with rubber channels and sandwiched rubber between the crates. I then secured the structure to the driver- side tie down. I'm probably going to further secure the structure by drilling through the base crate and secure into one of the seat bolts when I find the correct length screw. I made the crates out of anodized aluminum, high-density polyethylene (food grade) panels, aluminum composite panels, more aluminum sheet metal, steel reinforced connectors, medical-grade stainless-steel lift-off hinges, key-locking slam latches, and hundreds of rivets--and some extra rivets for Airstream heritage aesthetics.
. I make crates for SUVs as a hobby and this was my first design for a RV. I think they came out fairly well. Any thoughts are appreciated. Steve.
