My trailer.
Absolute waste of money - the only things that were any good was the Shurflo pump and RO unit.
The trailer is about 4 years old, used for 3 years, done about 8000 miles, rustly as anything, on its second set of wheel bearings which are now knackered again. Trailer mechanic say reason for bearing failures is that the axle is overloaded.
The pump box supplied was a water tight electrical box with a bypass tap and on/off switch. One of the reinforced plastic hoses split in the pump box and filled it with water. Stripped pump and left for a few months to thoroughly dry out - still working fine 2 years later.
RO unit supplied was supposed to be a 300GPD but had 3 x 75GPD membranes fitted.
