Yes, a 16 amp supply is nice to have, but a 6 amp is plenty.
A 6 amp supply is plenty for the fridge, tv, toaster, 1000w camping
kettle, microwave ovens, and other low-wattage appliances plus battery charging.
Anything higher only encourages the use of power-hungry appliances like deep fat fryers, domestic electric kettles, mini electric ovens, and 2kw heaters, etc.
Speaking from nearly 40 years of camping
, caravanning, and motorhoming experience I'd say rip out the 16 amp trips and replace them with 6 amp ones.
