OP, your issue is exactly why we didn't get a 5th wheel to start with. We started with a bumper pull travel trailer, two steps in, worked great. We wanted more room, really liked the Arctic Fox 27T with rear living and ended up finding one (we buy used) in great shape. We love it, but it sits much higher than our old trailer and has three steps in. We feel the difference but when it is just us, we don't go in and out constantly like it seems we do when camping with a group. When it is just us, we cook mostly inside (grill outside). We either out for hours or inside.. last weekend, after getting all the foodstuffs out to cook and eat as a group, we were tired of the steps.
Not saying to avoid higher trailers, just be aware when looking that some are much higher than others.
