Wendy and I live in Lowell,In. We have a 2004-3670RL. We pull it with a 2001-F350, 7.3diesel crewcab, Reese 16K slider. The only other addition is a superchip and what a difference! Since we picked up your 3670 in late June of 03 we have put on about 5600 miles. We try to stay in state parks if possible. this year we will be going around Lake Michigan, down to Arkansas, and weekend trips to In/Mi state parks. We started out tenting than: 18ft TT,26ft TT, 32ft TT. After looking at what Keystone had to offer Wendy and I got the 3670, my parents a Sprinter, my sister a Couger.
