Why don't you sell your car and buy a van, using the money to convert that instead? There's a bunch of videos of people doing this on tiktok and YouTube if you search for something like 'van life'.
the thing is that the car is very reliable. i dont want to take my chances with a van. it is the most reliable car i have ever had and I do not want to get rid of it. I was thinking if I used foam and fiberglass to make the body I could save a ton of weight. That way I can add weight in other ways. this thing has never had an accident, never had a break down because i actively get it maintained and it has always been maintained. I dont want to lose it for a van that breaks down constantly
i would also use a wood frame
Fair enough, Toyotas are great cars tbh.
I have just had a look online and this is the closest I could find to a community for what you're looking for:https://www.reddit.com/r/TeardropTrailers/
Judging by the OP you could be looking for something bigger than this though. Someone posted picrel on that subreddit and I can see the appeal.
