Winnebago Solis 59PX vs Coachmen Nova 20C

Winnebago · Class B

The difference that matters

Sleeping count splits these ProMaster vans. The Solis 59PX has a pop-top sleeping area as standard, raising capacity to four, plus a Murphy+ bed with L-track gear space underneath. The Nova 20C sleeps two, with a pop top offered as an option.

Bathrooms differ too. The Solis uses a swiveling 4.5 gal cassette toilet and no black tank, while the Nova carries a 19 gal black tank. The Nova's fresh tank is larger at 27 gal against 20, but the Solis has more gray at 30 against 20. The Nova's battery bank is bigger, three AGM batteries totalling 345 Ah against two on the Solis.

Each rides a ProMaster with the 3.6L V6 at 9,350 lb GVWR, carries 220 W of solar and a 13,500 BTU air conditioner. The Solis includes a 2,800 W gas generator and is rated to tow 3,500 lb against the Nova's 2,150.

Winnebago Solis 59PX: Small families or couples with guests who want four berths and L-track gear space under the bed
Coachmen Nova 20C: Two-person van buyers who prefer a plumbed black tank and more battery capacity.
