Adding Spare Tire Mount to GreyHawk

Travlr45 inspired me with the spare tire mount he added to his Melbourne, but I had to do things a bit differently as my Greyhawk has less room between the frame and coach than he had. Here is the mockup of the TECA #500-100 winch attached to a 2x2 3/16" square pipe between the frame rails. I'll weld it up in the light tomorrow

Ok finally brought the coach back home to take some pics.
I bought some 2x2x3/16" square pipe and some 1 1/4x1 1/4" square tubing thinking this would be a snap.
Unfortunately, unlike the Melbourne, my Grehawk has just under 2" clearance between the frame and the coach where I needed to mount the spare, so I was not able to put the 2" pipe on top of the frame.

I ended up cutting the 2x2 and welding some feet on it so it would sit inside the frame rails I then welded another chunk of 2x4 on top of the main cross piece to mount the winch to. This allowed me to get the tire up as high as possible, and to make sure I had clearance to run the actuator for the winch out the back so I can raise and lower the tire with a 3/4" socket just inside the bumper. I used 1/2" bolts to secure the mount to the chassis as my grey tank slides out toward the back where the spare is now mounted, so if I ever have a problem with the grey tank I can easily remove the spare tire carrier and drop the tank.

I mounted two pieces of square tubing in a similar manner about 11" in front and back of the center of the tire to draw the tire up against, but the bolts go from top to bottom rather than though the sides of the chassis rail due to the positioning of the BigFoot Levelers.

Can you tell me exactly which hoist and lifting hardware and how long the drive tube was you bought?

I went with the 500-100 RV Winch Assy and a 21" Actuator tube from TECA - I did have to cut a small amount of the actuator tube off to get the right fit between the MH body and bumper, so I did have to drill a new hole for the keeper that holds the tube to the winch.

Like Travlr45 I ordered directly from:
http://www.tecaassembly.com/rv.html
You'll have to call them to order, they don't have Internet ordering on the site.

Be careful. Although a tire will fit there and you can fabricate the winch system for it the frame rail extensions are not built to carry the load of the tire on the new Greyhawks. When I purchased my new Greyhawk the dealer sent it out to have the frame rails beefed up to Ford specification to carry the additional weight - I got the side benefit of a 7500# tow rating and 750# tongue weight (less the spare tire and carrier weight however).

Thanks for the heads up but I find it hard to believe that those frame rail extensions would not be able to handle the weight of a spare tire which is probably 80 to 100 lbs. including the the steel, especially considering the Reese hitch is also attached to the frame rails and would carry way more than that in tongue weight if towing a boat or some type of trailer.

As long as you deduct the 100#+or so from the tow dead weight (500#) rating you should be fine. The issue is people don't do that. My other problem was I am flat towing a Tahoe. The GM book weight is 5500# with driver and fuel. But when I weighed my Tahoe I found out that it was closer to 6500 pounds. The only way to be safe was to have the subframe beef up done to increase my tow rating to 7500 pounds and 750# tongue weight. The subframe beef up was done to Ford specifications. In addition I wanted rear skid wheels installed to prevent damage to the rear of the motorhome in the event I encountered a steep driveway or road. You cannot do this unless you have a sub frame beef done.
