New models with 4x4 with cabover bunk?

There are a few specialty manufacturers but prices are a little crazy.

As mentioned previously a couple things negate the benefits of manufacturers producing 4x4 versions:

The house an many won't stand up to any serious off road work. Once the frame starts flexing you quickly run into problems with it holding together. Google: Unimog RV and you will see what it takes to make a true off road RV. Probably overkill for what you need but you will find most keep the house separate and use a 3 point support system so the frame can flex independent of the house.

If it's just a bit of extra traction you are looking for, it's probably not needed or easily achieved thru other means:
- A typical pickup might carry 40% of it's weight on the rear axle. Since traction is coefficient of friction times weight, you have traction equal to roughly 40% of the rear tire with the least available traction. By engaging 4x4, you get 100% of the tire with the least available traction or about 150% more traction.
- On a Class C, it's probably closer to 70% on the rear axle, so you already start with around 75% more traction. If you think you need more, get a limited slip diff or better a locking diff, you address those situations where one wheel is in mud or loose sand and can often double the available traction.

Ultimiately a 4x4 will do better but if you are thinking of an empty pickup as a comparison, the class c will already have far more traction as a percentage of overall weight.

I really like that Tigervehicle. We once had a nice truck and truck slide in camper. I miss it. If it wasn't for a wife, I would grab that tigervehicle in a heartbeat.

I don't need to be four-wheeling, but just having it on dirt road excursions, getting off the road and boondocking and exploring all of the BLM trails and roads we have available in the West would be great.

Also Phoenix Cruiser. Phoenixusarv.com. Not sure if these have cabover bunk.

Thank you. I checked out Phoenix Cruiser and don't see the cabover bunk, but will ask them.

What's your intended use, if I may ask?

First, thank you for your responses above.

We are based in Las Vegas and will travel mostly in the southwest US on short trips. There are some dirt roads that we would like to explore. Some, while pretty free from vegetation, do have decent grades and sometimes rutted surfaces that may be difficult for traction. In addition, a little extra clearance would be helpful.

Also, while we don't plan to travel in snow or rain, it would be nice to have a little extra traction in case we end up in that situation.

I like the idea of the Winnebago Revel, but we really want two decent-sized beds. I haven't seen a 4x4 Class B that pulls off the two beds, thus the corner bed and cabover bunk of a Class C.

I hope Winnebago or others push the 4x4 chassis to models with just a bit more room and sleeping capacity.

I think there are a few reasons why 4x4 class C's aren't common. Probably the biggest one is that the usual van chassis employed are not available with four wheel drive from the factory, so any such model would have to use an aftermarket converter (like Quigley et al) or an atypical chassis.

More generally, though, there aren't all that many situations where a 4x4 class C makes too much sense. They generally have fairly decent traction in poor weather conditions (at least any one would care to be out in with such a large, unwieldy vehicle) due to having quite a bit of weight over the drive wheels. For going off road, they are wide, tall, have a pretty high CG, have poor turning radii and poor departure angles, all of which are rather limiting. Most typical class C structures aren't really designed to take the stresses of much rough off-road travel, either.

Four wheel drive also adds a good bit of weight, taking away from the (often already none too great) cargo carrying ability of the unit.
