I think it depends on what year you are buying and model. The Triton V10 before 2007 only had 2 valves. We added a Banks, which helped a lot. Without the Banks our 04 would trudge up the mountains at or below 45. Our current MH has the TV10 with 3 valves. It does better than the 2 valve with Banks.
Does not sound like you have many mountains to go through, just some hills.
Also of note is the noise and heat in some rigs. If insulated properly, both of those are minimized. In our 04 we had to shout at each other to be heard, but in current one the only time we raise our voices is a few minutes in the mountains whe the RPMs are up. Our 04 had heat and cold leaking through the firewall.
I believe a V10 is worth it, even if you are in it a lot, but take your time and pick the right rig.
