Where to even start with this one since this isn't your run of the mill 398M. First off this is the last year of the 18' garage so if you want the newest one you can get with the newest colors THIS is it! Upgrades like 8k axles, disc brakes, upgraded solar package with 2000w inverter, stage 2 Rockford Fosgate stereo, slide toppers installed on all slides and () Alcoa wheels ($2k) are just some of the options and upgrades. None of these include all the standard features which some of them are noted below. This unit is by far the best deal online and the only 2024 I could find!

Here at Landon’s RV, we specialize exclusively in late-model, luxury fifth wheels in the right condition at the right price— it’s all we do (aside from the occasional clean trade-in). No big-box volume sales here. Just a small family owned dealership where you matter and the units matter. Photos shown are of the actual unit — no stock images, no tricks. Mistakes can happen, so if you want anything verified or would like a video walkthrough, just ask.

Inventory moves fast, so reach out to see what we have coming in — some units never even make it online and you can join our mailing list to get alerted of new incoming inventory.

NO FEES — ever. No doc fee, no PDI fee, no title fee. No fees to make sure things work or camping fees IYKYK
