Hi John,
The Specialty Recreation Universal Replacement RV Skylight # SR89RR itself measures 25-1/2" wide x 37-3/4" long, so if you were measuring your skylight it would be larger. But regarding fit, it will fit over a 22" wide x 34" long cutout, so if you were referring to the 22" x 36" as the cutout, then it wouldn't fit, and we wouldn't have one that does as these are the largest we offer. view full answer...
Hi Janice; the Specialty Recreation Universal Inner Garnish for RV Skylight # SR57RR will fit if you have a standard 14" wide x 22" long cutout. We have no way of knowing exactly what is in your Lance TT so you will need to measure to confirm fitment. view full answer...
