Are all Tiffin models 12’10” or 154”. Going through Zion Mt. Carmel tunnel next week so with their 13’1” restriction which if Tiffin is correct I have 3” clearance. If you have been through it what was your height and do they measure you or leave it up to you to know your height? Any info other than refer to park guide I read already would be appropriated. Thanks

No, it depends on your model as my Phaeton is 13'2" to the top of hard surfaces. You must realize that your height is to the top of equipment like ACs, TV antenna, etc but your radio and CB antennas will extend higher. They will be scraping the top of the tunnel and 3" clearance is just too close for comfort. Is it worth the chance of losing some rooftop equipment? I have been through that tunnel on motorcycle and Jeep and I would never take an RV other than a small Class C or trailer through it. The tunnel is over a mile long and they have to shut down traffic from the opposite direction so you can ride the center line. They do measure the overall length and over 50' total is not allowed. Your safest bet is to route into Zion from the west side through Hurricane.

We were at Zion last Sep. with our Tiffin 32SA. We did not drive through the tunnel, we went back around on the highway to Bryce. The only way they allow big rigs through the tunnel is by a guide. They literally shut the traffic down both ways, it is not a favorable way to go, it causes hours of traffic problems for those driving autos.

I agree with Lt Dan. Not worth the risk. I went through that tunnel with a 12' high motorhome and it felt very tight. I would never do it with one approaching 13 feet.

Nope way too close for me.

I figure 13 6 on ours.

We went thru the tunnel in our winnebago 35U .. which if I recall correctly was the longest they would allow on that winding road .. with that being said it was an additional $45.00 for them to shut the tunnel down as I drove thru it .. toad has to be detached .. the tunnel is arched and dark .. not a lot of room for error .. and i'm not even talking about your height .. i would recommend against it also .. it seems to me one you get into the park I don't recall any convenient ways to make a U-turn .. what i know now I would have a plan before i drove the rv into the park..

I never go by their specs. Get a straight edge, level and a tape measure. get on the roof and find your highest point on your unit and measure it to the ground. I have even had the wife get out and watch going under questionable underpasses. The public doesn't like it but then again they are not replacing what i would tear up.

On our 18/45OPP the brochure says 12"7' to top of A/Cs. The highest point is actually the factory dome and it was measured at 13". I don't worry about the spring loaded cb/radio antennas since they flex.

I've only been through that tunnel once when I was a small kid, with my parents driving a station wagon towing a trailer. I'll never forget as soon as we entered it it got so dark the beagle in my lap got scared and wanted to jump out the window.

Here's a link to info
