When you arrive with a Rampless ground loading trailer, people will notice!
Ground loading trailers have load bearing moving parts that can fail when you need them most. Inspect these carefully before you decide.
Historically, many locally supplied trailers have been made from poor quality and used parts. Typically these parts will be galvanized or covered in a thick paint coating and sold as new. (Check this by simply inspecting the tyres, look for sprayed-over welds at your local trailer yard and move on from there.)
