Running AC On The Road

In a Class B or small Class C do you find that the overhead AC unit has to be run in addition to the dash AC when on the road, especially in the hot summer months? Or can the dash AC keep the MH cool enough? The reason that I ask is that the overhead AC needs the generator running to function and some MH's for sale do not have an on board generator. There are a few Class B's in particular that don't seem to come with generators which means when you are on the road or stopped at a rest stop you only have the dash AC or no AC at all when not moving.

    That was my experience too.....BUT I think it depends on whether or not there will be people riding in the "back" and what their heat tolerance IS. If both occupants ride in the front seats, you should be able to get by in almost anything.

    Even my 36' A cools the front seats good enough with just the dash vents.....but the last 10 feet of it is "garage" so there is only about 26' to actually cool.

    I too wouldn't have an RV without a generator but if you ALWAYS will be in a park with power you might be able to get by.
  • We have a DP and the dash air will keep the front end comfortable except when it gets over 100F outside for long periods. Considering that you will have a hot engine right there between the two of you, you may get warmer than you want in hot weather without a generator.

    I would not buy a MH without a built in generator and I wouldn't buy anpropane generator. We use our generator quit a bit.

    The Ford A/C in particular is actually more powerful than the rooftop unit in terms of cooling power, its drawback however is the relatively small fan.

    The trick is to open the rearmost roof vent wide open and set the dash A/C to point straight down the aisle. This will keep the front seat occupants cool but not frozen. The vacuum created by the open roof vent pulls the hot air at the ceiling level out and draws the cooler air from the front to the back.

    I've been doing this for decades. It works well.

    The dash AC will keep the cab cool but not the entire MH...baybe a small B might.
