We’ve had a great experience with our Wayfarer Van. Us two senior citizens assembled it without any problem. Our first major trip was from Austin to Guadalupe Mountains National Park where we slept in comfort in the van. The RAM Promaster mileage was a decent 27 mpg and the Wayfarer magnetically installed wall padding made for a quiet drive.
A recommendation when negotiating with the dealer: Check if things like the front floor mats and tire spare are included since the van can be sold in a very stripped down configuration.
