Hard to stay in lane on highway?

Agree with Luvlabs. Before you spend real money on suspension upgrades, give yourself some time behind the wheel to get used to the handling of a Class C. They tend to wander a lot more than a car due to wind and cross-wind conditions, dips and crown of the road, turbulence from passing big rigs and even from passing cars. Adjustment of caster by a good truck alignment shop seems to be the most common first attempt to improve steering , load the rig as recommended above.

I take claims of "handling like an SUV", after spending big bucks on suspension upgrades, with a grain of salt.

PS: Class C's have a harsh ride mainly due to stiff "box truck" rear suspension. Some have had rear springs modified for less stiffness. I advise taking breaks at rest stops every 100 or 200 miles, getting out and resting on solid ground to conserve your nerves.

I have driven many different size vehicles down the interstates including big rigs and when I drove my Class C home from Minnesota to California it was a totally new experience for me. It wandered, leaned, drifted on the trip home. I just adjusted the movement slightly with the steering wheel and also tried different speeds. My rig likes 65 MPH on the open road. If I go 70 it feels looser on the front end. I watch for big rigs and let the air disturbance push the rig a little and then it just comes back to straight with little effort on my part. Trying to steer to compensate doesn't work. Relax and get the feel of your rig, start out at slower speeds. It's been said that a motorhome is basically a kleenex box with wheels, aerodynamics don't exist.
Larger vehicles will definitely have an effect.
Alignment on mine made a HUGE difference, that and all new shock absorbers.
