You won't have any issues you can't handle with the 80 & RTT on height or width I ran it with four 80's two of them had RTT's but you will get pinstriping the trail is run regularly but its not maintained like a park so in places there is tight growth to work through. There is a possibility you will have to cut around falling trees or other obstacles. A storm blew through before we ran it and we ended doing a lot of cutting and winching to keep moving. We did a good job on trip planning and preparation we had everything we needed to handle most issues the trail could throw at us. Well worth it tooI've run several sections of the HWMT in my Taco, but never in my new to me 80. Not worried about pin striping, but I'm wondering if the 80 is likely to get deflared, or if height will be an issue with an RTT on top? Gets pretty skinny in spots.
