I have a gently used 2022 Momentum 399TH in excellent condition. It has a few factory upgrades including 330w solar panel with inverter, cooper tires, blind spot cameras both sides and rear, Gen-Y hitch, Onan 5.5kw gas generator with 12.5 hours, 60 gallons fuel (30g generator, 30g toys), 13’ garage, 48” cargo slide, 3-15btu AC’s, residential fridge and stove.
We have used it several weekends but never had a toy in garage and never used the rear 30g tank. We have never boondocked but start generator every month and run for 30 minutes. Garage has queen bunk and lower couches with table. Half bath in garage never really used. We always camped plugged into shore power and have decided to buy non toy hauler 5th wheel.
