You would naturally like more trellis space.
Here's how you can double your trellis space in 8 easy steps.
1) Build a four foot wide bed (farthest right). Note-your box does not HAVE to be 4 ft wide. Mine was. Reference step 2.
2) Erect a trellis using pipe, rebar, U-shaped brackets and trellising mesh. Make sure to connect the trellis to the back of the four foot box making it utterly impossible to reach the third square from either side once the trellis is covered with vines.
3. Spend the entire summer cursing yourself.
4. Have a friend like EG who's example you should have followed the first time.
4. When the summer season is over, move your trellis by first unscrewing the U-shaped brackets and nearly giving yourself a hernia trying to pull the pipe off of the rebar it's become fused to.
5. Move the rebar up one foot on both sides and pound it into the ground.
6) Slide the trellis over the rebar and use the U-shaped brackets to tweak the alignment and secure the trellis to the box.
7) Curse yourself yet again for not doing this the first time because now you can reach the third row from the back side AND plant on BOTH sides of the trellis, doubling your trellising sqft.
8) Thank the man for helping you since your Bert and Ernie arms wouldn't have gotten that trellis off of that rebar no way, no how. Thanks, Man.
The morning comes early. Sweet gardening dreams.
