Ron Hornaday was celebrating after a relatively straightforward victory in the Smith's 350 NASCAR Camping World Truck race at the 1.5-mile oval Las Vegas Motor Speedway gave him back-to-back series wins.

"I wanted this win really, really bad," said Hornaday in victory lane. "I finally won in Vegas."

The 53-year-old racer led for 107 of the 146 laps after having won pole position earlier in the day and finished in the top three in both practice sessions. However, the sheer volume of cautions during the race (10 in all, comprising 44 laps) meant that he was never able to pull out much of a margin at the front - although at least having the lead kept him out of trouble.

"This is just a dream come true," Hornaday said. "You don't get trucks like that very often, and I've got it two races in a row, so that's pretty awesome," he said, thanking car owners Kevin and DeLana Harvick. The #2 Kevin Harvick Inc. Truck now leads the owner points.

The cautions caught up both of the championship leaders coming into Las Vegas, with Austin Dillon finding the wall in turn 4 on lap 3 and James Buescher making contact with Blake Feese on lap 48. Both Dillon and Buescher ended up on pit road for repairs and finished well off the lead lap and down the final race order (17th and 21st respectively).

The other accidents to bring out yellow involved Max Papis and Max Gresham on the front stretch on lap 23; Max Gresham and Brent Raymer crashing on lap 42; Joey Coulter having a solo accident in turn 2 on lap 61; Justin Lofton an Cale Gale crashing on the backstretch on lap 124; and an accident between Jennifer Jo Cobb and Jason White in turn 2 bringing out out the final yellow of the day on lap 136.

A multiple car accident in turn 1 caught out Brian Ickler, Miguel Paludo, Ricky Carmichael and Ryan Sieg and resulted in a red flag for the clean-up on lap 31, and there were also two debris cautions on laps 13 and 117.

In the championship, Dillon manages to hold on to the lead by 5pts with Johnny Sauter now in second place, after Buescher drops to third place in the wake of his accident at Vegas. Ron Hornaday's race victory pops him up to fourth place in the points ahead of Timothy Peters, who is still well ahead of Matt Crafton who finished second to Hornaday in Vegas, and Todd Bodine who was fifth meaning that both make up positions after good showings this week.

There were no Cup regulars running in the Truck race this week, as the Smith's 350 was being held as the support event to the IZOD IndyCar World Championships at Las Vegas while the NASCAR Sprint Cup Bank of America 500 was being staged almost simultaneously on the east coast at Charlotte.
