Yes, the older FWC Hawk Models will be too wide for your truck.
They usually measure 64" accross the portion of the camper that sits in the bed / tail gate area.
Some Tundra trucks only have a 58" wide tail gate opening, other Tundra trucks have a 60" wide tail gate opening.
I'm 99% sure that the 2004 - 2006 Toyota Tundra Double Cab trucks had the 60" wide tail gate opening ?
(you might want to check your tail gate opening measurement)
If you have a 60" wide opening in the tail gate area, you could maybe keep you eye out for a used Hawk that was built in 1990, or newer.
(example: 1990, 1991, 1992, 1993, etc.)
Most customers won't find it an easy task to narrow the camper base on an old Four Wheel Camper.
Hope this helps.
