Guest Le Thou Posted January 30, 2008 Share Posted January 30, 2008 Is there any formula for working out what the towing capabilities of a motorhome with a gross weight of 3800kgs. Link to comment Share on other sites More sharing options...
colin Posted January 30, 2008 Share Posted January 30, 2008 I thought for all new vehicles it was as stated by manufacturer, not sure when this system started. Link to comment Share on other sites More sharing options...
Clive Posted January 30, 2008 Share Posted January 30, 2008 It will effectively be on the rating plate for the vehicle, probably on the drivers side wheel arch. It will be the MAX TRAIN WEIGHT. Take the MAM (maximum authorised mass) away from the Max Train Weight and you will have the maximum trailer weight remaining. If you read the manual however you will probably get two figures, one for a braked trailer and one for a non braked trailer. However non braked trailers are limited to I belive 750KG by legislation anyway in the EU. Mel Eastburn is the guru on all things weight wise and will probably pop up and correct me soon. Good luck C. Link to comment Share on other sites More sharing options...
Derek Uzzell Posted January 31, 2008 Share Posted January 31, 2008 Auto-Trail's 2007 model-year brochure gave the Maximum Gross Weight (MGW) and Maximum Gross Train Weight (MGTW) of a Miami 740 as, respectively, 3800kg and 5500kg. The following link may be helpful: http://www.dft.gov.uk/pgr/roads/vehicles/vssafety/requirementsfortrailers It's perhaps worth adding that the MGTW can vary significantly according to the exact mechanical specification of a chassis. For example, a 2003 FWD Ford Transit with a MGW of 3500kg has a MGTW of 4500kg, whereas 2003 RWD Transit equivalents with the same 3500kg MGW, have MGTWs of 5500kg, 5750kg or 6000kg depending on the engine type and/or final-drive ratio. There may be additional caveats in the vehicle manufacturer's handbook - for instance, Ford advises that, for altitudes exceeding 1000 metres above sea level, the MGTW datum must be reduced by 10% for every 1000 metres gain in altitude.

tonyishuk Posted January 31, 2008 Share Posted January 31, 2008 A passing thought, If you have Alko extensions on your chassis, it may effect the fixing of the towbar (as in where bolts can go without drilling the chassis) and this in turn may affect the weight the towbar can take. Might pay to ask. Rgds Link to comment Share on other sites More sharing options...
Guest Le Thou Posted January 31, 2008 Share Posted January 31, 2008 Thanks Tony but towbar already fitted. Link to comment Share on other sites More sharing options...
