Hi Ash,
I did a quick search and see your rear axle weight rating is 7,800 lbs.
If that is correct, 500 lbs. will likely be too much, unless your rig is very lightly loaded, with the weight mostly toward the front.
Beyond the tongue weight rating, which is based on a trailer, not the dead weight of a bike -- the rear axle will 'see' much more than the 500 lbs., due to the fact that it is exerting downward force several feet behind the axle.
There is a formula to determine the exact amount of additional weight, but for discussion, let's say it's an extra 300 lbs. That's 800 lbs. on the rear axle and 300 lbs. off the front.
Our View has a rear axle rating of 7,720 lbs. (Sprinter chassis). It also has a 500 lb. hitch. Our bike is a Suzuki DR-Z400 that weighs about 320 lbs. The carrier, security chain, and locks are another ~50 lbs. for about 370 total.
I would not want any more weight back there. As-is, we have the rear axle maxed out -- we even had an inner wheel crack! -- and the handling in some situations is 'less than ideal'. For example there is a highway in Nevada -- I think it is 395 -- that is posted at maybe 65-70 mph. It goes through a series of deep washes -- the hills are so steep that if you're doing the speed limit the rig practically leaves the road. In that sort of situation, even slowing down to 45-50 mph doesn't help much. The rear axle acts like the pivot point for a teeter-totter and the front end hits the bump stops over and over again (with brand new Koni struts) -- light, then heavy.
Granted, it might be a pretty wild ride even without the bike, but it's something to keep in mind.
Also any potholes and washboard roads are made worse, and a lot of stress is placed on the hitch and carrier.
If you go with a fixed carrier like we did (they're sturdy, cheaper, and much lighter -- but more work) you might consider buying a folding aluminum ramp. It makes loading/unloading much easier than the short ramp that came with the carrier.
Good luck!
