Regarding trailers, open vs. enclosed? Haulmarks look to be popular but so do the Featherlites. Cost is an issue, as always. Dual axle with some extra room. Most likely a 28 footer for support materials. Do any come with a driver's side access door? I live close to Elkhart Indiana which used to be the RV / trailer capital of the Western hemisphere. From the local news on the RV business and other suppliers, the industry is getting beat up pretty bad. Thanks, Upstaged in snowy / cold Michigan.
