Microwave and fridge

I am currently driving a man tga xxl with factory fitted fridge and 24v roadmate microwave.

My question is I will soon be upgrading to a man tgx xxl however it has none of the above, how easy will it be to remove and fit them? I am asking as I doubt the gaffer will pay man to do the job so will need to do It myself.

Any help would be greatly appreciated

Thanks
