The PUP to TT comparison is an apple to oranges comparison. While similar in many ways, each is better for specific situations. At times, it is hard to decide which best fits your outdoor style. If you want or need convenience, it is hard to beat a TT; if you lean towards mobility than a PUP is perhaps a better choice.
Another important factor is camping location; a hot sunny day with no hook ups is a lot easier with a PUP and 360 degrees of screens rather than a tin box with windows and no hookups or generator.
Also, life is a series of “windows in time” which means those “kids” are going to be teens with friends, and other pursuits. So, getting together for a family outing may be like trying to herd cats. It can change your time commitments and limit you camping opportunities. In my case I did not sell my PUP when I bought my TT, it was old and paid for and can sleeps 8 people It is the obvious choice when we need a lot of sleeping room or even when I want to go to an event myself with minimal hassle.
Our TT is 25 ft. sleeps 2 in the front bed and the breakfast nook could hold 2 more. The fold down couch is 62 inches which works for the dog. The TT is perfect for the DW and me.
So back to the obvious questions;
• What do you need to change to accommodate your family?.
• How will these changes affect your camping style?
• How long will you need these changes, before things change again?
• What will it cost you to make these changes?
These are the question every RVer must ask and only they can answer them.
Good luck
