For Sale: 2024 Jayco Jay Feather 21MML Travel Trailer Like New!

Lightly used only once, this travel trailer is in pristine condition and loaded with premium upgrades that make it perfect for both campgrounds and off-grid adventures. Yes, the outside needs a bath - been in storage for a year. I will ensure it is cleaned up for delivery. You might also note it still has 900Amp hours ready to go!

If you're looking for a travel trailer that blends lightweight towability, interior comfort, and serious off-grid power, this 2024 Jayco Jay Feather 21MML is built for you. I’ve only used it once, so it’s virtually brand new — but with upgrades that let you go beyond campgrounds.

Your Added Upgrades (Off-Grid & Power)

5 solar panels give you strong off-grid charging potential for off-grid use

3 × 300Ah LiFePO₄ batteries = 900Ah, giving you huge energy storage for running lights, fridge, electronics, and even A/C in many conditions without hookup. An additional power plug has been installed in the front so you can use a generator and short cord to quick charge from the back of your pickup.

Soft-start air conditioner (reduces startup power surge) which helps with solar/inverter setups and preserves system longevity.

What Makes This One Special

You essentially get all the solid build quality and features Jayco typically includes in the 2024 Jay Feather line — lightweight framing, strong insulation, modern finishes, good utility — plus significant ($10K+) off-grid power built in. That means less dependency on hookups, more flexibility in where you travel, and lower running costs for many setups.

Perfect for couples, weekend warriors, or anyone wanting a clean, almost new trailer with serious “go-anywhere” readiness.
