Jermey, you aren't going to like the answer.� The temp will barely have budged in 2 hours.� My stock fridge works as well as any and in�the heat of summer�I don't expect it to get down below 40 degrees until the next morning.� Runnng on 110 vs gas doens't make much if any�difference.� Running it overnight on gas is a good way to get it cold before filling it with food/beer for a trip.�� I am mostly satisfied with mine.� It uses no electricity and very little propane.� I added a fan inside the side vent to pull the hot air out from behind which helps during the hottest times of the day.
�
If I got a portable, I would get a smaller one that fits behind the passenger seat.� Seems like most people opt for the large one but that looks to me like it takes up half the inside floor space.

The portable fridge seems nice, but where would you put it?� Not alot of real estate in back. Then again, I am toting two kids and a wife also.�

I have the original Dometic in my '87 Westy. I have not really had the opportunity to� test it out. If I plug the van into shore, how long would it take to actually cool?� Someone told me, hopefully jokingly, that it will take a couple of hours just to get maybe 30degrees below ambient.

Other than the shocking price, that's very good news for
long-term-camping Westy owners.� I'm sure people would be interested
in hearing more about the internal size and hot-weather performance
of this unit at some point.

If I hadn't already popped for my Vitrifrigo, I'd be doing this:
http://www.compactappliance.com/FP430-Compact-EdgeStar-Portable-Refrigerator-Freezer/FP430,default,pd.html

Using the Dometic/Vitri space for storage, and add a 50W solar panel on the pop top to run everything.

Top loaders are MUCH more efficient and can actuallly store suitable amounts of mass-quantities to be
"out there" as long as the 50W panel will allow (about 7-8 full dry-camping days without recharge of any
kind, except solar).

Of course, having 140-200 amp hour aux battery set up, supports that above example.
