Any fridge will work better with vents compressor or three way will have the same amount of heat to disipate for the same load

Have always done this even with gas & works wellAnd don't forget that with just a little planning, for much of the time you really don't need to run the fridge during the night.
Keep freezer blocks in the freezer and when you turn in for the night move the blocks into the fridge and turn the fridge off.
8+ ish hours of ah saving, every night.
We've been looking at what solar panels are needed to support a 95l compressor fridge with freezer compartment (45 watts) & with 2 x 95ah batteries & one 100w panel it should be ok for 4-9 days without EHU depending on time of year & other usage. If driving during this time then figures obviously improve. If you or anyone wants to see the spreadsheet for this then just PM.Has anyone got a van with the compressor fridge? how does it work in practice and how power hungry is it? - we will have a twin 95Ah leisure battery bank and will probably add 100-200w solar - the feedback i’ve had to date indicates this won’t help and the compressor fridges are unsuitable for off- grid camping due to their current draw - somewhere between 50-100A /24hr which is a bit of a blow.

Just found out thanks to @gerry mcg a 95Ah battery would only really have 47.5 Ah accessible (50%) before the battery is at risk of damage from deep discharge & the spreadsheet figures supplied to us don't take this into account! Looks like one panel is more borderline than we thought (know some do manage with this but depends on usage & how often motorhome is moved) so would suggest two 100w panels are the way to go.We've been looking at what solar panels are needed to support a 95l compressor fridge with freezer compartment (45 watts) & with 2 x 95ah batteries & one 100w panel it should be ok for 4-9 days without EHU depending on time of year & other usage.
