I did not have the problem of kids, I could not fit on the throne with my back against the back wall and my knees against the front wall my simple solution was to angle the throne by about 30 degrees to the left where the door sits.
The door is hung outside the wall of the head, enough space to do the paperwork.
If you have a vent you might be able to replace it with a unit that has a fan and you can run that as a ceiling fan, other wise you are going to have a lot of modifications to do in order to secure the fan.
You want to get rid of the dogs?
Let them out with a pack of coyote's roaming around.
No more dogs,
One coyote and one dog, dog wins
One dog and two coyotes dog will keep up and be pretty mangled.
One dog and three coyotes, kiss the dog a goner.
Two dogs and 6 or 8 coyotes kiss both dogs goners.
We have coyotes where we are living now, and one animal alone will run from me, two will bluff to see what I do, three will make me really stand my ground with the nine ready, and I will try to keep all within site, when I loose sight of one, I shoot the nearest one and turn on the other ones, because the one I lost sight is going to be behind me.
Before you install the unit have the wife also check the height of the unit in relation to the ground, my wife is shorter than me and I am glad that I asked her otherwise she would not have been happy with the height of the handle.
As for some kid turning the unit forward and not being able to open the door, the plastic is not as strong, it will brake and let you out.
There should be a "stud" framing the door and the screws provided with the unit will hold well.
If we find that we have to wait in line and there are no chairs, I take the folding chair that we use for sitting outside for my wife, she can not stand for long, bad back and hips, that happened to us coming back and she had to get out with the cat in a carrier while I drove the RV to the X-ray place, it only took them an hour and a half to do that, big 18 wheelers in front.
Cargo van with no motor, you can not back up for more that a few feet before the steering goes side ways, then you nee to move the van around, how do you intend to do that with no power?
Rent a U-Haul trailer with surge brakes and that one you can back up any where, cargo van not a good idea at all, the grapevine is ok going up its coming down that the problems start.
Traffic in Puebla can be bad and trying to find a parking place will be a night mare, leave the unit at Las Americas, and either take a bus or a taxi, there are a lot of good restaurants around the Zocalo, there is one that has the Mole Poblano that is gooood. there is also a street that has artesanias, small street the bar in the corner is a must see, I do not remember the name.
Another good place to visit is Cholula, it has the biggest pyramid in the world, most of it is underground, there is also a mural that depicts the Pulque drinkers, I do not know if they let visitors in, I have seen it and it is interesting, there are also several miles of tunnels under the pyramid maybe you car go in side.
P.S. if you are claustrophobic do not go in the tunnels they are small and hot.
Put water in pot, place pot on stove burner, turn burner on, drop coffe grinds in pot, boil water and coffy untill dark and smelly, place sock (used is better) on coffy mug create a small dimple on sock por coffe into sock and mug.
Now you have a good aromatic coffe in a mug, starbucks can't compeete with this one.
One time in Tehuacan I had dinner at the fancy restaurant and got as real good case of Moctezumas revenge, the next day the next door lady recomended the locat shamman "curandero" local witch doctor, he made some tea with the leaves of some bushes from his garden, within half an hour I had no more Moctezumas and for a long time my stomac was bullet proof, then I returned State side and gues what, I got Lincolns revenge.
There is another medicine that helps, "CAOPECTATO".
Before the 1968 Olypiic games they tried to find out where people got sick, it turned out to be an eye oppener, they found out that the fancy restaurants had the dirttiest kitchens, and the cleanest, the taco stand and the restaurant at the open mercado where clean and the food was always fresh, since they would run out of food, whereas the fancy place would have some food spoliling in the freezers that was being served to the clients.
The other source of Moctezumas is in the salads that may or may not have been irrigated with tainted water and may be washed with non potable water, I alays ask for bottled water, Penafiel and ask that the bottle not be opened, that I will return it if they open it, I carry a bottle opener on my key chain at all times.
I would contact the Police Department and ask them what storage facility would they use to store some things, as in would they use that facility and then rent the smallest unit to store my weapons, on an inside unit rather than one that is accessible to the out side, do not let any one know what it is that you are storing at all, and take the units early in the morning right at the time they open the facility.
The Marine was released last night and the weapons have been confiscated, never ever take weapons into Mexico not even any ammo, a single spent cartridge will get you in trouble, as for where to store fire arms I can not give you any help.
We are North of Palm Springs, California we now have broken the parkas and the sand sky's, it is very cold for the high desert for this time of the year in this area, and this past summer was not has hot as years past.
This may be a very cold and wet winter for all of the USA.
Get your flue-shots!
Buy a tarp that covers the top and at least 2 to 3 feet on both sides and the front and back of the RV, and have it tied down, on the center roof of the RV plave a ridge manufactured with white pvc irigation pipe.
The construction of the ridge shoul look like an inverted "T" the upper part of the T long enough so that it does not tip over, place several of these inverted T's and connect them together at the bottom of the T's with t fittings and pipie running from one to the other, remenber that the "T"'s are upside down.
This ridge keeps the tarp of the roof and allows some of the water and snow to shed off, make shure that the tarps is tight on the sides, even if you have place more gromets to pass ropes to tie the tarp.
I hope it helps a little.
Those type of programs are more alarmist than what it really is, most of the gang members will be asleep in the early morning, they start steering in the afternoon and conduct most of the business in the early evening and through the night, Oakland is on the other side of the bay, in San Francisco itself you will have areas of gang activity.
If I a am going to stay in one of the big towns for some time, and plan on going out at night I go to the local police station and ask them where it is safe and where not to go, they always give me the areas to avoid, I also use common sense and look for individuals with ill fitting clothes and tattoos standing around on corners.
Most gang members are more concerned with the rival gang than you, if you stay in the areas where the tourist go you will not have trouble, I do not want to frighten you but you have gang members in the town where you live, the bloods and the crips and the ms13 ( mara salvatrucha) are already operating where you reside, so is the Mexican cartels.
It is a cancer that has spread everywhere in the USA, some people notice it some are oblivious to it until something happens and then they panic.
Go about your travel and enjoy the areas in San Francisco, you will be safe.
