Front end alignment

[rikeps59]

I have the 2014 Thor Vegas, bought it at 32,000, I didn't pay attention when I was buying it when the owner said he put new tires on the front.
First trip, just over 3000 miles, I could see the front outside of the tire was wearing. Had it aligned. Next trip, just over 3000, I had to replace the front tires?? what's up with the alignment on this? anyone else have this problem.
Thanks
