I would like to use the van for weekend trips while I plan out a full fledged electric setup. I will be going with 24v system and already have D2 heater from the past van and will be adding a Dometic CFX3 45 fridge. Looking for some ideas to create a temp setup that will help me to use the heater and the fridge.
My idea was a bit more simplistic and intended to help you make it through the 6 month gap between now and when you have the electrical system that you desire for running the air conditioning. It may or may not work for you.
We use two different size cases to build the products:
~ 20 x 30 x 12 H inch
~ 20 x 30 x 20 H inch
________________
The larger case systems have an insulated battery pack area, so they can be used with Li or AGM, 2 or 4 batteries. ( Lifeline size 27 or Battle born). Example:

I wouldn't knowingly put LiFe batteries into an uninsulated version if the customer is likely to use the system for use in areas that receive snow.

The smaller case is the size of a full size suit case and can be used in any angle, but the battery pack area is not insulated, so it is really only for Lifeline size 24 AGM batteries.

Depending on the application, we wire them 24 or 48 volts internally, then use DC - DC converters to make the desired regulated 13 volts, USB, etc on the output as needed.
I have one of these small case systems that I use as a demo unit in a 1x1 configuration.
- 1 kW inverter
- 1 kW-hr usable AGM capacity (2 x 80 amp-hr wired in series)
Since it is AGM based, there is a fundamental assumption that there will be some solar charging and ideally also some alternator / battery to battery based charging.

My early morning coffee thoughts were to rent a 1x1 system to you for 6 months while you figure out what you actually need long term. I haven't done "rentals" before so it isn't a well formulated idea, just an idea.

The pros of this idea is that it is quick and can power the items that you mentioned - even ski trips to Mt Hood.
The limitations of this concept is that AGM batteries really need fairly regular 3+ hr charge cycles. It would not be able to keep up with your fridge + heater without at least some solar power installed.
The amount of driving that you are talking about would not be enough to keep an AGM battery pack sufficiently charged.
If you temporarily mounted a couple of flex panels on the roof, that would help it work.

I don't have other "temporary" solutions, so if you are focused on going down a LiFe path right away, that would have to be purchased and built. That takes some time.
