Similar here..... When we built the Transit all the cooking was electric
3 x 100ah flooded lead acids
2 X 100ah
solar
Basic
PWM solar controller
Durite VSR
(though we did have a high output alternator due to it being a ex mess bus)
Never struggled for power even in winter with the eberspacher running full tilt 24/7
And 12v Waeco coolbox...
Though we always moved on at least after 2 nights.
When we got the motorhome I was shocked how poor the available power was (obviously most folks spend their holidays on Umbilical power)
Fast forward to 400w of
solar
3 x 100ah AGM
Victron mppt
Victron b2b
Compressor fridge
Refillable gas bottles
Etc etc
And now 300ah Ecoworthy lithium....
The only time we've ever come close to running short of power was last November when on a site for a week in cold weather with little
solar harvest due to cloud cover
And not driving to allow engine charging.
