Front bench reducing floor space: Well Jim, yes & no. The total floor space under the table is less because of the bench in front. However, since the table is smaller and it pushes over the bench, you have a foot of space to step from in front of door towards trailer front & table top.
Drawback is some people would want larger table.
FYI, we had a 6' guy sitting on the front bench (it is narrower than the side benches) yesterday. He may have been being nice, but he said it wasn't uncomfortable. However, we'll give him a side settee if we're playing cards for evening.
