Looking at options to cool our recent purchase of a 68 Aristocrat Lo-Liner. Any suggestions? Husband is thinking on top at the vent opening.

to VTT. As nccamper says, if you get into 1968 Lo-Liner rebuild blogs, you will be able to see how the wooden framing inside the walls and roof (ceiling) is put together and the dimensions of the wooden framing itself. IMO, the original Lo-Liner wooden framing is not structurally sound enough to handle a roof mounted AC unit unless you beef up the framing considerably and then you still have the drag coefficient on the roof with the wind (speed) at highway speeds. Better to consider concealing a small a/c unit in some of the other areas discussed in the threads nccamper provided, as a start. A final comment would be that the lines of a 1968 Aristocrat Lo-Liner are too darned sweet to be broken by a roof top A/C unit.

my 1970 shasta had an original roof top a/c. the rafters of mine were made two different ways. some rafters were made from 2x4s 1.5" thick and others were made with a 3/4 thick x 2 on flat with another 3/4 thick x 1.5" wide turned vertical making and "L" shape. also several were beefed up with the aluminum extrusion which was used for joining the ceiling panels for cosmetic reasons and also for stiffening op the rafters. see pic. also there was either one or two steel 3/4 x 3/4 angles that wrapped around 2 of the rafters or maybe just one if i remember. when i pulled the old a/c off the roof i was barely able to do it alone. i was amazed at the weight of the a/c.
