I've been thinking of upgrading my 845 lance camper to one with a slide. Preferably a 971 or similar dry bath camper. How stable are the srw trucks with the additional weight?
Dullies are by design more stable. Do you need one with the new camper? No clue as I dont know how much it weighs. But regardless of the actual weights, loading the same camper onto a SRW and a dually, the dually will feel more planted on the road.
