Unit A/C or dash when driving?

2016 FR3 30 DS: Walk through tech said to use unit a/c when driving as it keeps battery's charged and sales guy that knows everything - yet doesn't own an rv - said use dash a/c as that cools plenty. What are your opinions? Thanks!

IF the dash unit has enough in a given situation, just use it. If it isn't enough, use the generator and the roof unit as well. That is what most do. The batteries should be charged by the alternator when the engine is running.

Sales guy was correct. Tech guy needs training.

You shouldn't need to run the generator to keep the batteries charged while cruising down the highway...


If the Dash AC won't keep up,, crank up the genny and turn on the roof unit. Make sure all the ceiling vents are closed, and also run the dash AC in MAX.

We typically run the genset when driving. Not necessarily to charge the batteries, but more so for running the house AC. Run it when you need it, though I think you'll find the dash AC lacking.

As everyone else has said, when the dash isn't enough run the unit AC. We do it on and off depending on the kids level of whining about being hot, then in 5 minutes they are cold so no winning for me. Running the genny isn't needed to charge the house batteries when your driving.

Both...

I run the unit A/C if the temps are above 80, especially if it is sunny. We almost always have the dash A/C going too.

The engine alternator charges the coach and chassis batteries. The generator only charges the coach batteries.

Running the dash AC on max should only be done until the air coming from the dash vents is cool enough. Then turn the switch to AC or norm.. Running on max all the time will cause icing on the lines. Same process as running a refrigerator/freezer on too cold of a setting. Keep in mind that an air conditioners function is not to cool the cab but to remove warm air from a vehicle.
I do agree that if the dash air is not cooling you enough (especially when having other passengers), run the gen. and turn on the house air.
If it's just the wife and I, we'll sometime hang a blanket from the overhead bunk to keep as much of the dash air in the front area. So far has worked well.

Nope. Generator, or more accurately stated, converter/charger on the FR3 does charge the chassis battery.

Hanging a blanket or the privacy curtain to keep dash cooled air in the cab area is a great idea.Usually just the two of us and our dog, who rides between us. Now why didn't I think of that? LOL
