bench seats for Frabill trekker 2?

[perchkid]

i just bought a trekker before christmas and have used it several times. it's great for two people but when i bring my other friend along it's hard to have three people in the tent with two seats. i was thinking about building a bench seat. any ideas

You could build one with the existing seat frames or call Frabill and see if they will sell you a third complete seat setup.

Personally I don't know how three would fit in there comfortably.
I find mine perfect for two.
