Bumper pull toy hauler, adding a second A/C unit

So I have a 34' unit, open garage and would like to install one of the new A/C heat pump style units so I can have heat and cool in my bedroom. My concern is the front of the toy hauler slopes dowward for about 15 feet to the nose. This would put the A/C unit at an angle and not flat like most all I have seen. Just curious if this is a problem running the unit or not?

Next I know I left out some information needed so let me have it with the questions!:S
