Hi. Just bought my first motorhome a Roller Team Autoroller200. On getting it home and having a good poke around I was suprised to find that there doesn't seem to be much supporting the back of the body behind the rear axle, just a short couple of chassis extensions held on by self tappers. Doesn't seem much to me. Is this normal. Also how do I get the spare wheel off. It appears that is has never been off in it's life as there is what seems to be the wheel trims wrapped up and wedged between the wheel and the van floor. The van doesn't have any trims fitted.
