$60k is the MSRP and pretty much nobody purchases for MSRP. You can purchase a brand new 2016 Sierra for $37k from RV wholesalers. Read through the forums for both Sierra & Sandpiper, since they're sister brands. It'd be wiser to have a warranty because there sure seems to be a lot of quality issues with these 2 brands.
We looked at a few 2014 Sandpiper models last week. Left over inventory on a dealer lot in Michigan. We were kind of shocked at the poor quality in so many areas of this brand. 4 inch crack in the exterior fiberglass in a slide corner, front door out of alignment, underbelly cover all warped with big gaps, most interior cabinet doors were misaligned, water dripping down the interior of the storage doors, rear bumper already rusting, bedroom closet door wouldn't even close it was so out of alignment. Awning lights all warped & becoming detached. These were just things we noticed from walking through it. Imagine what's happening behind the walls, ceiling & floor of these units.
Just read about this brand before you make your decision.
