Slide when mounted to truck

as a fellow horseman and owner of a truck camper with a slide and having trailered my horses coast to coast doing the Horse Hotel route. I don't take the camper off the truck and I don't disconnect the trailer. I off load the horses get them bedded down watered and fed and muck the trailer and fill the water buckets before stuff can freeze over. Then I pull to where ever I am spending the night at the facility (usually where they have a electrical hook up for me) Level the truck, extend the rear jacks to just touching , extend the slides and call it good. Make sure you have your Coggins and Horse health Certificate or they will not allow you to off load your horse for the night. and make sure you enter all weigh and ag stations with signage that all vehicles hauling livestock must enter. have proof of horse ownership with you too.
