Hit a tree in the rv park

Well it was a great weekend camping at jetty park at Cape Canaveral. But I had a oops moment as soon as a i got there. I have been back my rvs up for many years now and consider my self a simi pro at it. So I pull to the sit the " holds a 39foot rv" I do what i have been doing for many years I back up get the rear tires on the slab line my with the edge then back up looking out the drivers side till i get the front tires on the slab. This time as soon as my front tires hit the slab i give i little gas to bump it on. Little it I realized there was a tell palm tree dead center for the slab about a foot from it. Needless to say as soon as I pump the gas to get over the slab I hit the tree ruining the bumper of my RV. I have to say I've been doing this for a long time never once as I seen a tree park in the back of a slab in the dead center Outback close. Normally I would hang the RV over the back of the slab by about 6 or 8 feet Soma water and electric lines up. So yes I blame myself for not noticing that tree but at the same time I'm thinking who in the world would put a tree dead center of a camping pad that was supposedly rated for a 39 foot and -36 foot. Had I not put the front wheels on the slab the front of the motorhome would have been in the street.
