Like BradW said and Sidecar mentioned also as to TC construction, we also would have the older made TCs and with aluminum exterior as it always looks new if keep clean which we do. Brad's is a 1996 Lance 500 and ours is a 1997 Lance Legend 990 and has been totally problem free and 20 years old now with way over a thousand nights use and over 100,000 miles of travel. One piece aluminum roof and never a leak or a need to replace. Very heavy but lots of room inside and has a true dry shower in its nearly 11.5 floor length so no slide needed and no need to open the slide to even enter as there's not one. Everything totally usable anytime! Excellect insulation and alway very warm inside at well below zero F. If we wanted a new TC, we would simply buy one!
