You cant buy a mini and expect a rolls royce!!!
If buying new you would spend between $10,000 and $20,000 for anything of reasonable quality. And if you want more luxuries start heading towards the $50,000 + price range.
A half decent set of wheels and tyres together with a HD axle springs and brakes would cost more than the $2200 you spent on a so called off road trailer.
No offence but you either need to spend some of your hard earned or put up with what you have.
Ps you can pick up decent used campers a few years old for between $5,000 and $20,000. Maybe you should consider used???
