Been Moho owners for decades and see people going from carrying less than the bare essentials to loading up with "stuff" for every conceivable circumstance (and then some!).
Are you taking the MoHo home to load up or are you taking everything in the car and then going straight off?
I always suggest having a tryout on your driveway (even if it is just for a few hours) where you do everything that you will do when away and if you have forgotten something, you can pop inside to get it.
Park, level up, cook, eat, make drinks, wash up, shower, toilet, heating, load the fridge, are you drinking the on-board water or taking bottled, restrain Ddogs when travelling, make up the beds, watch TV, read, charge phones, imagine coming back from a long walk wet & tired (made worse with Ddogs!), feeding the Ddogs, where are they sleeping, be ready for them wanting to go out to the loo in the middle of a dark, wet night, are you going to be sitting outside, how will you keep the Ddogs on your pitch, BBQ, will you be regularly moving the MoHo or parking up for a few days and walking and/or using public transport, topping up with water, draining waste water, emptying toilet..........?
So many things to consider which eventually becomes second nature but can overwhelm the beginner and spoil the first couple of days until you get into your stride.
Have fun.😁
