Just wondering who all has a Grand Prix with a bike rack in tow.. mine
is a 99 grand prix, 2 door gt..

According to Uhaul.. i can take at best a class 2 hitch (3500 lbs)..

These were the two they list:

37103    Stealth Receiver    2    3500    N/A     Black    $119.95     Buy now

36241    Heavy Duty 1 1/4 inch Rec    2    3500    N/A     Black    $149.95     Buy now

I'm really not sure what the difference is, as they both list at 3500
lbs and class 2.

What I'm wondering is.. has anyone put a 4 bike rear mounted rack
system on their car.  Does it cause gas mileage to drop by half and
require extra transmission fluid due to strain (someone told me it
may, but i kinda doubt it).

I will be hauling, for now, 2 steel bikes (adult) and 2 kid size
bikes, eventually, they will be say 2 steel and 2 aluminum weight
ones.. either way i dont think the total weight will exceed say 150lbs
back there.

Also.. I want to get the right hitch, so that I may be able to tow say
a waverunner on a trailer or an atv on a trailer (i'm guessing this
may definitely induce drag etc?).. not sure what those combos weigh
though, or if I'll end up just putting them on my next vehicle, an
SUV).

So again, I'm not sure what the difference is between the stealth
hitch and the heavy duty 1.25" or what typical 4 bike racks cost.

I thought about getting a 4 bike rack for the roof, but those appear
to be about $500 vs about say $160 for the rear one, plus I figure I
will use the hitch for other purposes, if feasible.

Thanks for any advice.
