trailer size and campsites in National Parks

I did a search and did not find any threads on this topic. I am sure there are, so I need some help finding them.

Based on what I read on the Parks site, along with several web sits, Several National Parks limit the combined length of the tow vehicle and the trailer to 40'. My truck is 19' so that means the trailer needs to be 21 feet or less. Is this accurate? (the rule, not the arithmetic)

I am in the process of buying a travel trailer and visit the National Parks, I want to choose the right size.

Please elaborate on the 40' rule

Thank you

  • Personal decision but I would at least get one large enough to have a walk around bed and a slideout usually in the 24'-26' range. Some of the older COE parks were built many years ago when a 20' trailer was the norm.

    Others will chime in with more knowledge then I on the subject.

    Every park is different. Sometimes length limitations are due to site size and sometimes to trees or rocks along curves in the roads to the sites. I have been hosting in a NFS campground that has a part of the sites in which rvs are limited to 28 feet, but that means trailer under 28 feet. It’s because of the road; there are sites there that would fit a 64+ Class A or fifth wheel. You just can’t get one that size to the site.

    I wouldn’t choose a trailer based on such a limitation, if I were you. Don’t put the cart before the horse. No matter what size you choose, there will be places you can’t take it. Make your choice based on floor plan and features.

    It is true that smaller goes more places. But too small is no fun everywhere. In addition, know that rules like that 40 foot rule are both arbitrary and flexible. Nobody is going to take a tape measure to your rig and deny you because you are 6 inches too long. Or 2 feet too long. The rule is to guide folks, not forbid them. If you are skillful maneuvering a slightly longer rig, you’ll be fine. If you are very low skill, you might not be able to use even a slightly shorter one.


    I have owned a few boats and was skilled at backing, but I have not owned a trailer, this will be my first one.

    I appreciate your insight. The trailer I choose will be my home for a few years. Thus, making the right choice is important. With regard to your thoughtful reply, I am now looking at the Lance 1995. I toured one yesterday and it seemed about right.

    Do you mean 21' is too long or too small?
