Need B+ MPG, deciding between B & B+

The old T1N B would get very good MPG numbers. Also, they may be old, so they may not be allowed in most CGs, but the small Cs based on the Toyota truck (pre-Tacoma) frame also get high gas numbers.

The Leisure Travel Vans Unity based on the Mercedes Benz Sprinter 3500 gets 20 mpg.

22' b+, 10-11 @ 65.

I have owned both a B Pleasureway 2009 model 350 and now own a 2010 Itasca Cambria 28B 450 V10. Gas wise will be better in a Class B.
8 to 11 mpg in B+
14 or better in a B.

Our 24' Win Aspect B+ with a V10 Ford 350 chassis gets 10-11 MPG. When towing a Honda CRV, we lose another 1 MPG.

Regarding fuel economy alone.

Given identical chassis & engine, say an E350 for example, the difference in fuel economy between a B and B+ is generally influenced by these factors.

- Weight
- How many rear wheels
- aerodynamics

If you are willing to settle for a B+ that is just a little larger than a B, you won't take a rediculous hit in fuel economy. The mpg problem comes when you go for more house.

Every duel rear wheel B+ model will have reduced fuel economy compared to single rear wheel van B. But keeping the size similar like for example the Phoenix Cruiser 2100, special ordered with the smaller V8 engine and no slide out, you will not be far away from a B in fuel economy. For one or two mpg, you get a fully featured motor home with practical features like a real bathroom, a large fridge, good storage, a real dinette, a good stove, sink, counter space, real plumbing, and lots of water and sewer capacities. Not a confining tiny rig with novelty features. And if you priced a PC-2100 without a slide out Like This One, and V8 engine compared to a nice B rig, you'd be saving a lot of money on the purchase price which more than covers the loss in fuel economy.

Given identical small B+ rigs, the chassis generally compares as follows.
- The Chevy/GM gets 1 mpg better than the Ford E350-V10.
- The Sprinter diesel gets 1/3 better mileage than the Ford E350-V10.
- The Ford E350-V8 gets 1 mpg than the Ford E350-V10.
- The Ford E350-V10 gets 1 mpg better than the Ford E450-V10

A good reference point would be a Phoenix Cruiser 2350 offered on the Ford E350-V10, E450-V10, and the Sprinter V6 Diesel. Driven conservatively and not towing anything, the E350 "Trip Average" will be around 11 mpg, the E450 around 10 mpg, and the Sprinter around 14 mpg.

A cross between a B and B+ is the Winnebago Rialta which gets between 15 and 20 mpg pending model year. Made from 1996 to 2005, there were 3 different engines from weakest in 1996 to the strongest introduced in 2003. But with strength came lower fuel economy. Though marketed for 2 to 4 people, it seems ideal for going solo.

If mpg is your priority then you would be better off with a B.

B+ mileage will vary depending on how heavy the B+ is. Currently getting about 9mpg with our B+ which is nearly as aerodynamic as a B. Do not expect to get over 10mpg. Our units traveling weight is about 12500 lbs.

That said, I like to the room in the B+. You are going to spend weeks or months on the road........I would probably swallow hard and choose the B+. Lots more comfort.

2013 25' Coachman Concord 220 B+. Chevy v8 4500. 10.5 mpg. average.

I had a 21-foot Dynamax Starflyte B+ with Ford V10. It got 10-11 MPG.

My current 25-foot Class C with V10 gets about 8 MPH.

Basically the larger frontal area of a B+ or C compared to the B causes the MPG to decline by quite a bit.

Best MPG will come from the M-B Sprinter vans with diesel. These cost about $10,000 extra up-front and diesel has been more per gallon so the payoff could be a long time coming.
