RV Description
Optional Tow-Vehicle available
Turn-key. Immaculate. Ready to go. If you want a top-tier 5th wheel without inheriting someone elses to-do list, this is the one.
2021 Keystone Montana 3761FL Legacy (Front Living) with 1.5 baths, non-smoker, meticulously maintained, garage-climate controlled stored, and everything works exactly as it should. Nothing needs fixing.
Why this one is different
This immaculate Montana 3761FL LEGACY is built around power + reliability + premium factory options:
Solar upgraded to 1200W
2 Battle Born lithium batteries
Factory 3000W inverter + energy management system
SoftStart A/Cs (reduced startup surge easier on 30A hookups and smoother starts)
Full body exterior paint
6-point hydraulic auto-leveling
Disc brakes
Dual pane windows
Slide topper awnings
Many more premium options
Meticulously Maintained
We just had Affinity RV go through the coach and take care of the typical little things that loosen up over time, so the next owner isnt dealing with random gremlins. Receipts available for serious buyers.
Front living means your whole crew can actually hang out without stacking on top of each other and its one of the best layouts Keystone ever did. Tons of storage. Easy to tow. Comfortable for extended trips.
Optional tow vehicle available
If you want a complete, ready-to-go setup, we also have the matching tow vehicle available:
2020 GMC Sierra 3500HD Denali
Duramax diesel | 4x4 | SRW | short bed
48,800 miles

Clean, strong truck set up to tow this Montana right now
$58,000
If you've been hunting a clean, turn-key setup, this is it.
