The axle spacing on equitrek trailers is greater than most standard trailers, expect to scrub out tyres quicker, and watch the all up weight, easy to tip over the 3500 kg mark , especially if you get one of the equitreks with the living on the front, lots of space to fill up with all the things you never needed to take with you in the first place
As with all glastonite or fibreglass boxes, if they become damaged and water gets in, the panels de-laminate, the structural integrity of the trailer is then compromised and can be very costly to repair.
Stick with ifor williams or rice/richardson , you will not go far wrong
