I did not notice this forum subjet before,but being a horseman,I use to have a riding school with an inside arena,
we used mostly " white horses" so they had to be clean in the morning for the students to use so to come back to
your question, it all depends on the type of maintenance and time you will put in to upkeep those big guys,
we used to clean the stalls 3 times a day nerver left any poup! or urine in the stalls,the floors were of red spuce
covered with 12 in. wood chips ,under the wood was crushed stone and there was a space of 1/2 in. between the 2X8X3 planks
they lasted about 2 years in the center and more, close to the walls.But of course it was commercial so it may not
apply to your needs but I hope it will help you take the right decision.
