With only 3 weeks to go before I set sail in my promaster I am trying to tidy up loose ends. I was planning on carrying a collapsable ladder in the van but have decided it takes up far too much space and I will want to access my roof often. Any recommendations on rear door ladders? I was looking at this one https://www.streetsideauto.com/p/su...MI8bLLhIf41wIV27jACh3SwwHNEAQYBCABEgLtyPD_BwE by surco as the price seems right and it will arrive before my 12/26 departure date. any experience or other recommendations?
