I, much like others here, mainly boondock off the beaten path. 

I've been in a few areas that I couldn't get the Truck and Camper in together, well, nicely.. Yet in. The rPod will go where basically any other 'commercial' trailer will go. I don't consider the 'real' Overlanders as commercial, though they are becoming more popular. 

My next trailer will be a true Overlander and I will build it. 

We never found a spot we couldn't get the 177 into.. approach and entrance roads that were crap was an issue a couple times. Most parks have at least a couple sites where the Pod fit fine, (but may not be available for the dates you want.. etc etc) though a couple times parking the truck was an issue, and we ended up with it in overflow parking or something. We also used a tent site more then once.

There are occasionally vehicle/trailer combo length limits.  Getting in to  Chisos Basin at Big Bend, they recommend a limit of 35', I think.  I don't know if they enforce it, but you will be very frustrated and will annoy a lot of people if you try to exceed it by much.  One of the main roads through Zion has a combo limit.  The Road to the Sun in Glacier NP has a combo limit of 20 feet (which seems like a odd way to say trailers not permitted.  There are great campgrounds on either end though.

These are the ones I know about.  I'm assuming you're asking about road restrictions, rather than camping spots to back into.  And I'm not talking about back roads at all, which should almost always be avoided with an RPod.  (The definition of "back road" is subject to discussion.)

Check websites or call before planning a visit if you have any doubts.  I've never had much trouble.

The Road to the Sun length limit is on all vehicles or combos.  At 29 foot bus won't do.

That's where my statement of 'common sense' comes in. I will say many a class 6 dirt road has been nicer than several of the major highways I've traveled, though at reduced speeds. 

Originally posted by GlueGuy We have commented on the Glacier/Going to the Sun Road when we were there. As it happens, our F-150 is 20' plus 4", so theoretically would not be allowed through WITHOUT a trailer. Maybe they don't measure it all that closely, but it could make for some interesting workarounds to get to the other side.

It's been a few years, but I seem to recall why they have the restriction.  There are some pretty tight turns, on inclines, that would be very hazardous for the driver as well as other traffic.  I suspect they enforce the spirit of the law more than the letter.  (Your 4" probably wouldn't get you pulled over.)

I can't help but wonder how many vehicles with trailers use the road because they are under 20' total.  A SmartCar pulling a tiny teardrop?  Maybe a motorcycle with a trailer.

Greetings:

I MN where I live, some of the parks are modifying camp sites for longer units.  You don't usually find folks with large 5th wheelers or trailers at state and national parks.  They tend to go to full service private campgrounds with 50amp outlets, water and sewer.  This fall, I had fun watching someone with a new large motorhome park in a tight spot at a State park. He did manage it after a number of tries.  

At the Devils tower, they have a large parking area, before the drive up.  You can drop your RV there.  Yet some folks drive them up.
