I tow a Jayco Jayfeather Sport 165. It is about 2650 lbs dry, and max GVWR is 3500 lbs. Pulls like a dream. Comes completely self contained, with microwave, A/C, full size permanent bed with bunk above, dinette that makes into double bed, oven, amplified TV antenna, stereo radio/CD, awning, portable outside BBQ that hooks up to propane system, awning, extra outside shower, large 5.5 cu ft refrig/freezer, fiberglass exterior, etc. I tow locked out of OD at 3000 RPM at 65 MPH running LT235/85R16's (32 inch equiv.) w/4.10 LS rearend. Normally get 10-12 mpg. 10 if towing in mountains or wind, and about 12 if towing more level ground with less wind. This is in MT. Also use equalizer hitch. Love the trailer/perfect for Sport Trac.
