I went from at 31 foot gasser with a 15 foot toad to a 45 foot DP with a 20 foot toad. It took a little getting used to. I still examine my mirrors carefully when making sharp or tight turns. Here are the issues I've encountered.
- I'm way longer now and have to use my rear camera (not the side camera) to tell when I'm completely safe to change lanes. If the rear camera says I'm good, then I look at the side mirror (my primary safety) then my side camera before changing lanes.
- My toad no longer tracks within the track of my MH. On my old coach if my coach could clear a path, then my toad simply followed. There was zero danger of my toad hitting anything as long as my coach made it. Now, my toad cuts corners and even though I've made it, I find my toad climbing curbs and coming much closer to signs, fences, fire hydrants, etc.
- I'm seated in front of the front tires now. That definitely takes getting used to. I now have to enter an intersection by a lot before turning and I hang over the edge of most roads while my front tire is safely on the pavement.
- Acceleration is much slower now when I had the gasser. I doubled my horsepower, but tripled my weight.
- I'm much taller than before as well. So although you didn't mention height, that makes a big difference. I'm now 13 feet, 4 inches tall vs 12 feet previously. Trees are the bane of my existence. I find myself looking at clearance maps and reading bridge signs now far more than before.
I don't think I'll ever be as quick going through campgrounds and tight roads as before. I think I'm used to it after 6 months, but I'll always be cautious and slower than before.
