I live in a tin can down by the river.
View from the driveway, coming in from over the bridge looking south, the tin can is barely visible:
It's a 1986, 34 foot, Comfort 5th wheel. Was given to me so I'd have a place to live - four years ago.
The section over the hitch (designed as bedroom) is storage.
I've nothing to pull it with, so not going anywhere anytime soon.
With that in mind I stocked up on propane:
A view of the tin can and tarp:
Windstorm hit hard this winter - dropped a tree on the school bus and had a couple of other trees threaten camp:
Which reminds me of Leska. Her place got slammed last month. Lot's of damage.
Here's a photo from two years ago, storms were so bad everything was shut down, was delayed ten days getting home, Greyhound, Amtrack, Airlines, highway all stopped. Here's a photo of Leska & I - the day I arrived in Portland:
Schoolie (Retro fitted school bus) is where I'm moving after It gets outfitted. Wood stove in bus:
So this is what the view from the tin can down by the river is - when we look North at the bridge:
The whole Tin Can thing is a play on Chris Farley and David Bowie.
The Chevy I get to drive (1963 - loaner):
Close friend and his son took these lions out, interesting mount?
Anyhow -- all that to bring some bone fides to the RV/travel trailer, are you sure you really want to - conversation.
It's doable to live in tight quarters. If you're not handy and poor (cash strapped) - I wouldn't suggest it.
So far have during the last four years had to replace;
12 volt water pump,
12 volt propane furnace,
propane/12 volt fridge ( took the door off made into pantry), replaced with small electric.
propane water heater (went with on demand),
2 - 12 volt marine batteries,
propane regulator,
shower faucet,
vanity faucet,
kitchen sink valve o rings,
oven still non functional (parts are unobtanium),
replaced lighting fixtures with LED - florescent bulbs are very expensive, and surely there's a few more things.
OK - then there's power and water.
Fortunately both are available here. Unfortunately voltage is low because it's a long run to the source, and, water requires a tank refill when 50 gallons is tapped.
Then there's sewer - Which I'm going to skip over for now.
On the flip side - when the powers out, no problem. Have a Honda EU 1000 inverter which powers 12 volt and AC systems via 120 volt AC - (water, furnace, lighting, refrigeration, and comms). Communications is router, wifi, desktop computer, and phone. The little Honda EU 1000 ran for six days straight, 24 hours a day - used just about 5 gallons of gas.
The storm that took the power out (think Texas):

Other considerations - food storage, have to really think it out in advance, frozen foods, foods that cannot freeze, and dry goods. Space is a premium commodity.
Laundry - sucks without your own. Covid shut down my local laundromat. Takes a lot of water and energy to keep clothes clean.
ETA - forgot about being over run by mice, couldn't keep up. Was getting two or three a day. Then the bears came to visit. Came home one day and a sow and two cubs got inside, there was a trail of inside items leading out to the river. The pinnacle of which was while eating breakfast, Yogi had entered the trailer. Was watching a youtube and didn't hear the door open. They are crafty after they've fed inside.
Hope this helps.
