I appreciate your experience and advice Lincster.
Based on the posts, we eliminated the 24' and larger TH's.
The 21" has an empty weight almost 3k lbs under his tow rating.
As for hitch weight, he doesn't need to fill the fresh water tank until at the campsite and can carry all the camping toys etc in the rear of the trailer lightening the front even more and not adding to his gvw on the truck.
As stated, he could use my 3500 drw if he wants to load up or travel longer distances or in the hills.
Thanks again
