In your area I would guess you may see some Northland campers , since they are built in Nampa , they have similar layouts as Lance and are a well built camper, been building them a long time
I have a Lance 500 Legend , its real close to a 1010 in size and layout , loaded they can be about in the near 4000 lb range , if loaded with care maybe 3600 lbs
Aluminum roof , will still need some attention at the front and rear seam , and at penetrations , but the field of it is good for a lot longer than I would ever have to worry about ( my life )
