Slide Adjustment Bolts on White Hawk 27DSLR?

[campingsue]

We picked up our new White Hawk on Thursday, drove 200 miles, camped 5 days, then drove 200 miles home. On our way home, we stopped to fill up and upon looking over the trailer, I noticed 2 long bolts sticking out from underneath the superslide. I had not noticed these bolts before. Of course, I worried, but my husband said they were tight and it should be safe to continue home. I took pictures and sent them to the Service Manager of the dealer we bought the trailer. I believe he called these "adjusting bolts" for the superslide and to not bother them. One of the bolts is underneath the superslide and is in front of the first axle. The other bolt is also underneath the superslide, but it is aligned parallel to the low water drain. Has anyone heard of these and have seen the same type of bolts? I do have pics, but not sure how to upload them.
Your advice is greatly appreciated.
