Practically new (Dec 2025) very rare Tune M1 topper on Full Size Chevy with std 6'5" bed (inquire as to availability of truck). Includes installation & Inspection to transfer existing 3-yr warranty (If you don't want those I will deduct them from the price). Basically it has 6 windows instead of the very common 4. It is VERY roomy. I am just over 5'10" and I easily fit crosswise on the 78" bed. The height is 80" popped up and you can pop up front, or back (e.g. lunch) or both. There is 50" of headroom with it closed. The camper has many accessories, including:

Hest queen mattress 60x78 (more comfortable than the one in my house)
270 Awning (never used)
10# Tune propane tank with rear mount (never used)
Driver's side Full window
Rear Full window
Pass through window to cab
Maxxair Fan
Insulation package
Vinyl Window rain guards (4)
Rain gutters
See "tuneoutdoor.com" for basic Tune M1 details
Sale includes ICECO electric frig/freezer 40 qt

Paid over $21k plus the ICECO less than 5 months ago!!! LOVE this topper but must sell it.
