Does a 22 foot B+ fit in a regular parking spot?

We have a 22 footer. It fits in most spaces for parallel parking and we have no trouble in the average lot. Since it takes up every inch for parallel parking,we generally look for a space with a little extra such as an end or near a hydrant. We have been surprised at hoe easy parking has been.

You should have no problems at a parking lot for grocery stores. You should try for spaces away from the rest and take up two spaces .

The lines on a parking space vary from 18 to 20 feet depending if the space is angled or not.
A 22' long vehicle can't completely fit into a 18-20' space.

However. We drive a 24' Class C and it's quite easy to find a space on the outside perimeter of most lots. Like the other answer about the big dually, we do partially encroach onto another space.

Go for it.

My Tiger is 20 feet long and 87 inches wide. I try to get an end spot at the curb or in a parking lot. That usually works. Getting out of the cab door can be a problem with vehicles on each side.

I am thinking that your Gulfstream is wider than the Tiger.

I don't know, but my crew cab pickup is 22' long, if that helps. Do I fit in a regular sized parking place, well, depends on what's in front of me. I do take up my half and usually a couple of feet of the spot in front of me.
