The Voyage V3538BR is a destination Travel Trailer for hookup-based RV resorts: dual slides, 100 gal grey tank, 50 gal fresh, queen bed, full bath, theater seating. The Voyage's missing dry weight is a real spec sheet gap to confirm with the dealer.

Pick the Airstream Basecamp 20X if…
Pick the Airstream Basecamp 20X if you tow with a midsize SUV and you camp where pavement ends. The X-Package and 3,400-lb single-axle weight are designed for forest-service roads, BLM dispersed sites, and trailhead basecamps. The aluminum monocoque construction also holds resale value far better than typical stick-and-tin. Best for an active solo or couples adventurer in the Mountain West or desert Southwest who treats the trailer as a basecamp at the end of the road.
Pick the Winnebago Voyage V3538BR if…
Pick the Winnebago Voyage V3538BR if you want a flagship dual-slide rear-bedroom Travel Trailer for hookup-equipped RV resort touring. The 38.83-ft length with two slides plus theater seating gives a real living-room feel when parked, and the 100-gal grey tank supports daily showers for an extended stretch. Best for retirees in a 3/4-ton truck who do seasonal relocation between RV resort destinations and care about indoor space.
Frequently asked
Are these really cross-shoppable?
Only on price. The Basecamp 20X is an off-road adventure rig; the Voyage V3538BR is a flagship campground destination trailer. They share a price band but solve completely different problems.
What's the dry weight of the Voyage V3538BR?
Winnebago doesn't publish a dry weight for the V3538BR — a real spec sheet gap. Confirm with the dealer before assuming half-ton compatibility.
Which has bigger tanks?
The Voyage by a wide margin — 50/100/50 fresh/grey/black vs 23/28/21 on the Basecamp. The Basecamp is sized for short dry-camp stays, not hookup-light extended camping.
