Here is some additional information. My Dad is 61 years old and would not have any physical problems getting around a travel trailer. The trailer is an 2005, but in excellent condition.
I firmly requested he sleeps in the TT for a few reasons:
We don't get a long well... things might get ugly if we are together this long without our dedicated areas.
We have different bed times.
We like different HVAC temps and watch different TV shows.
His 2 night stay turned into 8 nights and I would like to be a deterrent from this turning into an annual thing.
We have spare rooms, but none setup a bed. I would honestly be more comfortable in the TT compared to an air matrass.
He is allergic to cats and our kitty rules the house.
