HHR getting ready for the adventure

Sounds like it does not have much of a towing capacity or a strong roof. You will just have to work with what you have in terms of an interior capacity for sleeping or use an SUV tailgate tent. But if what you really want is a comfortable home on wheels you might consider trading it for something that has more abilities.

Roamer, the tent that gets the most accolades from the folks at Burning Man (severly high winds are the norm) is the Kodiak. Either the 10x14 or 10x10. It's easy for a single person to erect and goes up quickly. Best prices are usually from here : https://www.competitiveedgeproducts.com/Flex-Bow-Canvas-Tents_c_12.html

I cannot afford a camping trailer like "little guy, my pod etc". There over $12,000cdn and require lisencing and insurance a added cost I cannot afford...

Have you looked at Runaway campers? 
http://runawaycampers.com  looks like they have a striped down model called "For Starters" that's about $3600 USD. 
I don't know how you feel about towing but these are light 700lb.ish. I have a home made 4X8 very similar to this. I don't fine myself crawling around in it, most everything is in reach just sitting in the door way. It might work with your knee. 
Just wanted to let you know there are less expensive TTT options out there. And Runnaway is not the only low cost manufacture out there ether.
