|Comfortable all year round – does not absorb heat in summers and stays warm in winters.||Cannot resist moisture and water 100%.|
|Reasonable price – about $800 for average-sized trailers.||Is susceptible to termites and other wood-boring pests.|

This type of trailer flooring is more durable than wood and, with proper maintenance, can even get you a lifetime warranty.

Might not be a good choice for easily-spooked horses.|

It is resistant to heavy foot traffic.||The main drawback of composite Rumber materials for horse trailer flooring is that there may be gaps between tiles. This can lead to water seepage and drainage and invite rot.|
