Yeah but they didn't make Landrovers with an aluminium chassis and a steel body.
That chassis will flex all over the place without the rest of the caravan to support it so it'll need plenty of reinforcement as well as the cracks repairing.
If the OP is going to do that with a steel frame then he might as well just knock up a new trailer using the hitch and axle. I don't see the point in keeping the aluminium bit.
