Guys,
Long time reader, first time poster....
I have a SLEE rear bar on IFS 100 series. To be honest, I have been worried about this issue since purchasing the bar in Australia a couple of years ago and sought opinion from those who owned one.
I tow a Tvan camper that weighs approx. 1.5t loaded. I have just completed an 18,000km trip into some of the remotest areas in Australia with this setup and likely a little over GVM etc and absolutely no problems with the setup.
Before leaving I checked the tension in all mounting bolts and used Locktite on all bolts etc. The setup is rock solid and given that I fitted the bar myself and looking at the old towbar side by side with the SLEE bar, I would have to say that I would trust the SLEE bar more so than the original "rated" towbar.
All that being said, I never got pulled over for 'compliance' checking or weighing, but have heard the rumours that others had been checked out on the roads. I guess running this system is 'running the gauntlet' a little but I am confident that it won't fail and be the cause of any serious problems.
With regard to safety chains, I welded a heavy plate, under the receiver with some largish holes to accept rated shackles, similar to that which you see on the various towbars. Likewise all good.
The biggest problem for me was that because the setup is manufactured in the USA and that towbar hitches are Australian, there is a discrepancy in size between the hitches. The receiver is, from memory, 2 inches, whilst the Aus towers are 50mm and I find them to be a little loose and prone to rattling, unless there is significant towbar 'load'. I bought an anti-rattle hitch but am not that keen on how it all works and the difficulty in getting the towbar off with that arrangement. I plan to experiment with some "shims' on either the receiver or tow-hitch to resolve this problem.
Otherwise I really love the bar. The quality is excellent, whilst not being TOO heavy on the rear of the vehicle.
I will try to figure out how to upload some pics when I have the time....
Cheers,
Mark
