Will these be enough space to maneuver?

Rusty Bolt this was where I was headed as well. If your driveway is concrete especially if its the standard 3000psi mix your bobtail will destroy it over time. And yes a bobtail is heavy enough to do precisely that. If I'm having a concrete slab poured I'm using a 5000psi mix and using the hell out of rebar on a surface that has been tamped.

 

The consensus is make the door wider. Truck is 8.5' wide, mirrors add an additional 6-8" to each side (1' to 1'4" total) leaving you 1 to 3" on each side to clear, assuming you don't want to fold the mirrors in every time you put your baby away. Not much wiggle room. Also, I wouldn't mind doing it in a daycab with a window behind me to cheat, but with a super-long sleeper like that, I think the extra width will make it more realistic target to back into.

Any driver on here will attest to the difficulty of, say hooking up to a trailer that is oriented at a 90 degree angle to you, behind you on the right. You will be backing in on your blind side, so looking out your driver side window won't help much. You will get to know the turning radius and how to set it up with practice, but those pavers under your steer tires will probably crumble as you crank the wheel and jockey back and forth.

Please tell us what that sweet rig is for. I'm hoping it will be pulling a race trailer with a sprint car in it to all the dirt tracks in PA and OH next summer!

 

Another thing that works good is to have them put two 1/4" thick groove about an inch deep in the concrete so that it divides the floor into 4 equal quadrants. That way as the floor settles and cracks, it will usually crack in the grooves, where you won't ever see them.

No matter how big you build, it will never be big enough.

 

Most commercial garages have 14' wide doors...go big or go home.

 

I'm looking at my mirrors in my truck and I'd say there is easily 10ft or more there edge to edge.

 

The Shop we worked out of as kids was old and had 10 ft doors.

The old Viking only fit because the old man had the mirrors adjusted narrow!
Well both the old S Model 13 letter Sh##Spreader, and The steelnose DM bulldog, with a Big KittyCat in it That I ran, well I'id have to yank on a mirror in order to just squeak through!!

As far as floor and driveway goes, strip all upper soil and get to hard virgin ground, use a fairly clean coarser stoned gravel (depending on your ground 12 to 20 inches worth) once well compacted (and I do suggest using a compactor even if waiting a yr.) If you stick with gravel it can be racked and lowspots filled in easily.
Blacktop does not holdup to parking, no matter what!!!
Concrete is the best, the key is on a solid base, steel reinforcement. and shoot for 6 inch or more. 4inches is fine for cars but unless the base is perfect won't handle big trucks.

 

I actually stand corrected. My father put a 12' wide door on his shop, not a 10'. Still relatively tight though.
