they can weigh as little as 4000kg using medium-tensile or lightweight high-tensile steel, meaning more load can be carried on fewer axles and tyres, subject to static rollover thresholds not being exceeded, and less fuel is wasted.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can <a href=\"\/\/www.trgroupau.com\/vehicle-rentals\/skels\/\" data-type=\"link\"
