Had a little brain wave last night, am going to try a long piece of baling twine tied to my folding step. Hold on to the end when mounting and chuck it over the back ramp.Maybe you can attach a (telescope) stick to the step so that you can reach it from the saddle? Make sure to not spook your horse though.
On my 7.5t I just stand on my grooms door steps.MY lorry is 7.5ton and I have a similar problem, I have one of the metal folding ones at the moment https://www.ebay.co.uk/itm/156426558660?_skw=follding+metal+steps&itmmeta=01JCGR3NPGP5FWDVEQW2M5VSTT&hash=item246bbfdcc4:g:LisAAOSwqO9m86kX&itmprp=enc:AQAJAAAA8HoV3kP08IDx+KZ9MfhVJKmei/xt+Jcr8ubfqONBSHMaL27L32U/JUah5NtSqxZ5CK7tK73KZcDzaNXs454tspKzaEIEW5c+DWqcfA9WyK8ns4Zgmmpy90qqtR9tq8HbfwdCL+Tn6lfeXJGo3YcuRlNPxqWs0qjtef1Y7KtrtzPEZ54fAq1iovlI94QBTtNScHzUk2tqKjP7jZonO/Jy+WjsGuN4j3yksvrRo4MgDWBATGGDY60YzQIzLdbOHmS6FXe6+vX3DFarK6iD7nT4qi0nMpXz73szozXM8S5zfLk7bMDsVINcQ+1zkUvFVvDLDA==|tkp:Bk9SR7rbjpjkZA&var=457525078554
I always leave my ramp down so this would not work for me, am thinking of getting a light weight shires one as when ground wet the legs sink in
anyone got idea for horse box steps??
