The internal frame of the jeep lends itself to modification. Having your skis inside keeps them out of the salt that cars spray up. Also, it's easier to load and unload them and you dont end up looking like you washed your car with your ski jacket. In these photos, the skis are positioned diagonally but I've carried them in parallel with poles as well. The doggie collars go on the frame. The skis are held together by a velcro strap purchased from home depot. it's in the tool section and goes by the name 'husky'. I'm sure you could just string some velcro through the doggie collar loop and around the skis as well. or just use string.
