Legitimate concern with ultralight flooring.

Wife and I are about to leave for vacation in our 2020 Outback and have a viable concern with the flooring which is maybe 2" foam sandwiched between thin luan.

Here's where it gets interesting.
My youngest daughter "21" wants to bring her boyfriend who is an absolute mountain of a man at 6'4 420lbs.

They are staying in a tent beside us but will be in and out of trailer for a week.

It's a sensitive subject but do you keep this mammoth out of trailer or just roll with it ?

He's a super nice guy and don't want to hurt his feelings or upset daughter.
