New TH, basics questions

[sheepdoggin2]

Even though I lurked here while researching my purchase, I just joined this site. Thanks to all those who posted so much info for me to peruse while gathering data.

As you might guess from my handle, I use the TH to haul my Border Collies to sheep dog trials all over the country. I upgraded from a TT TH to the 5th wheel. I just came back from the maiden voyage (225 mile round trip, 2 nights). Upon return, I noticed a horrendous metallic squealing noise as it rolled past me on the drive (DH was test driving). We put it on the trailer ease, wheels spin fine with no grinding, etc. But I noticed all the springs are completely dry and may be the source of the noise. Should they be greased and quiet or is some noise normal?

I leave in 3 weeks for a big trip up through Colorado (including over Wolf Creek Pass). I travel by myself, DH stays home to take care of the farm, bless him. Should I trust the brand new tires it came equipped with, or assume they are junk and replace before I go?

Thanks for your input!

That nosie was probably the brakes engaged and using friction to stop.
However, some springs do have grease fittings to them, but most don't.
