Now almost 4 years old the synthetic deck in mine is still like new. The stuff cuts and routs just like soft wood. Because i chose to use the thinner choicedeck fascia boards from Lowes i did not rout the runner grooves but simply laid them on top. I spaced the runners to cover the seams and slightly routed them to fit under side bed rails. I too was worried about exhaust heat with only 7-8" clearance but it hasn't been a problem. Having the rails sit proud of the bed material has prevented any scuffs. Again my only regret is not bolting bed in BEFORE tank was installed.
