5) Its top speed is 60 mph
6) It slows to 25 mph climbing grades
The fact of the matter is that I don't think your vehicle is safe for Interstate Highway travel. Period. Full stop.
Study after study by federal (FHWA, NTSB), state, and academic researchers have shown that speed differential is at least as important as speed per se in determining highway safety. You yourself note how scary it is to be traveling 30-40 mph slower than the rest of traffic. It is not everybody else on the road causing safety problems. It's you. No one can tell you how to make this trip safely because your vehicle itself makes every moment that you're on a road with a greater than 55 mph speed limit an accident waiting to happen. It's up to you to keep out of everyone else's way, not vice versa.
If I were you and I had to get that vehicle cross country, I'd allow an absolute minimum of 10 days for the task and stick to surface roads rather than Interstates. I wish you luck. You're going to need it.
