How much do those containers hold?? While they might look snazzy mounted there, have you thought about what their weight mounted that far forward will do to the weight limits on your tow-hitch & the Spyder suspension?
I thought the tow-ball down-load limit was down around 40lbs or so, regardless of what the overall towing weight limit was?? Surely mounting any extra weight way forward like that on the tow arm/hitch is going to make the towball download faaar exceed the down-load limit for the Spyder hitch?? And regardless of whether you have a BRP approved tow hitch or anything else, that excess weight on the towball hasta be pounding the crap outta your suspension every time you tow even if you aren't riding 2-up!!
Wouldnt it it be a lot better to mount them up the back? Or at least pressed hard back onto the front of the trailer body instead of so far forward; so that you can at least try to balance the load out easier by putting something heavy towards the back of the trailer/behind the axle??
Just askin??
Regardless, I do wish we could get something like those RotoPax fuel containers here in Aus, they work well & make securing them onto anything fairly easy....
