Hi Scott!
We had two Coleman popup campers, before we bought our TrailManor. The lift system on the TrailManor was one of my reasons for buying it. It took about 40 turns on the crank to lift the popup; the TrailManor lift system is remarkably easy to use with minimum effort (just pull each section toward you and the lift system does the work). And, unlike your popup camper, the lift system doesn't use cables, pullies, and lift channels made of aluminum.
We haven't done any travel on bad roads for any distance, so I can't speak about long-distance travel on poor roads. But, we haven't had the recurring problems (leaking sink, problems caused by cheap construction materials) we had with our Coleman campers. Also, no hot end bunks caused by sun beating down on canvas (or cold end bunks in fall season).
Happy Camping!
