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.
